The capabilities of modern telephones go far beyond voice communication. With equal success, they can be used to store and edit files and, of course, to connect to the global network. Since mobile standards are most often limited by providers, owners of gadgets based on Android and iOS most often use Wi-Fi technology to connect to the Internet. But the presence of a Wi-Fi module in a mobile device alone does not guarantee a connection to the network.
It so happens that the phone does not connect to Wi-Fi, giving errors or notifying the user about the impossibility of connecting. Most often this happens due to a failure or incorrect settings of the device itself, but incorrect router configuration, modification of system files, installation of custom firmware, inconsistency of communication standards, infection with viruses and, in rare cases, failure of the Wi-Fi module can lead to the same results ... So, let's try to analyze in more detail why the phone does not connect to Wi-Fi and how it can be fixed.
Incorrect password entry, temporary failure
This error is usually issued when the Wi-Fi network cannot recognize the device connected to it. The reason is most often trivial - the user makes a mistake when entering the password and, as a result, receives a corresponding message.
Check if you entered the password correctly and try to connect again. Also note the name of the network. The Wi-Fi module on the phone detects not only your network, but also other access points that may have similar names, for example, mydoms and mydons. Make sure you are connecting to your network and not to your neighbor's network.
If up to this point there were no problems with authentication, try first restarting the smartphone and the router itself, perhaps there was some kind of temporary failure. Your phone still cannot connect to the Wi-Fi network? Delete the saved network in the WLAN settings and try to reconnect.
The above example is the simplest, but more often than not everything is a little more complicated, being associated with incorrect settings of the router itself.
Router settings
You connect to the network, but the phone does not connect to Wi-Fi, it says WPA2 or WPA is saved. After a few seconds, the message "Authentication error" appears. If the password is correct, there is most likely something wrong with the security settings of the router. It may be that the phone says "Saved", but the connection is still not established. It's easy to get into the router settings, you just need to go to the internal address in the browser 192.168.0.1 or 192.168.1.1 ... It is more difficult to understand its interface, since it can differ significantly in different router models.
By default, login and password are used to log in. admin / admin(look at the bottom on the case). Before making any changes to the router settings, remove the network from your phone, or at least disconnect. It is also advisable to create a backup copy of the router settings - if you suddenly get confused or do something wrong, you can always recover. After making changes to the settings of the router, it also needs to be rebooted.
Region
Now a little more detail about setting up an access point. First, try changing the region.
In the settings, this option is located in the section Wi-Fi - Advanced Settings, c - on the "Wireless" tab. In other models, it may be located in a different location. In a word, you need to first study the interface of your router. In the regional settings, the country in which you live should be selected, although this is not critical. Save your settings and reconnect.
Network mode
A much more important setting that can prevent the gadget from connecting to Wi-Fi is the wireless network operating mode. This is almost the main reason for the authentication error when connecting to Wi-Fi on a phone that may not support the current mode. There can be several modes: B, G, N, etc. If you have B / G / N mixed, install it, or you can try experimenting by choosing one or the other mode. Pay attention to the channel as well. It should be auto.
Security options
Find the security section in your router's settings and try playing with the options. It is desirable that the network authentication be set to WPA / WPA or WPA-PSK (if mixed, enable it), encryption - AES, the key contains only Latin characters, only numbers, or both.
After changing the settings of the router, reboot it, re-establish the connection on the phone. Unfortunately, the two methods described above can cause problems with connecting other devices, for example, a laptop or TV, if they do not support the changed parameters, so everything is not so simple here. If the password has been changed, in any case it will also have to be changed on other devices.
Channel width
It is highly unlikely that this will solve the problem, but just in case, you can try changing the width of the Wi-Fi network. In D-Link routers, look for the setting in the subsection Wi-Fi - Advanced Settings, in TP-Link - Wireless Settings - Channel Width... There are usually several available options: 20MHz, 40MHz, Auto and others.
Filtering by MAC address
Each electronic device has its own unique identifier - MAC address. Find the MAC filter subsection in the router settings and make sure that filtering is disabled.
If it is enabled, determine the MAC address of your smartphone, check the settings in the router and, if necessary, exclude the phone from the “black” list, or, conversely, add it to the “white” list.
Phone stuck getting IP address
Another common problem is the device getting stuck at the stage of obtaining an IP address. The phone does not connect to Wi-Fi, writes "Obtaining an IP address", and this message can be displayed for hours. The cause of the problem, again, may be hidden either in the settings of the mobile device or the router. The latter is indicated by problems with connecting to Wi-Fi and other devices. A DHCP server is responsible for distributing IP addresses to devices, changing the pool of addresses and the router itself in the router. If it is disabled, your device will never receive an IP address.
Is DHCP enabled?
Let's check the DHCP operation. The location of this setting differs from router to router. In TP-Link, you need to look for it in the Local network or LAN section, in D-Link it is usually located in the subsection Network - LAN.
The mode must be set to "Allow". Instead of a drop-down menu, the "Enable" and "Disable" radio buttons can be used in the router settings. Here, we suppose, everything is also clear.
Static IP
You can solve the problem of obtaining an IP address forever by registering a static IP in the advanced connection settings of your device.
To do this, click on your connection in the list of networks, select Change Network - Advanced Settings - DHCP - Custom(in earlier versions of Android, you will need to check the Static checkbox).
In the panel that opens, enter the IP address 192.168.X.YYY in the appropriate fields, where X is 1 or 0, it depends on the address where you access the router's settings (you can try both options), and YYY is any number from 0 up to 255.
The gateway must correspond to the address of your router, we leave the prefix length by default, DNS 1 (8.8.8.8) and DNS 2 (8.8.4.4) do not touch. If you have other data instead of those indicated in brackets, do not change them either - they are given by your provider. An exception is DNS 2, which can be left blank. If something is not clear or you doubt the correctness of the data entered, it is better to contact the support service of your provider - it is their direct responsibility to connect the devices of their clients to the network.
Automatic bug fixes
If you encounter an authentication error when connecting to Wi-Fi on Android, but your mobile Internet is working, install the application from the Google Play Store Android Wi-Fi Fixer... This utility is analogous to the Windows Connection Diagnostic Tool and is designed to find and automatically fix Wi-Fi connection errors on Android mobile devices. Once launched, the application checks all network settings and tries to connect to Wi-Fi bypassing.
Other reasons
The above examples of problems and how to fix them are the most common. In reality, there may be more reasons. Why won't my smartphone connect to Wi-Fi? Perhaps you installed an incomplete proxy server program, caught some kind of virus, rooted the device, changed the firmware, etc. Here you need to look at the circumstances. There have been examples of antivirus software blocking wireless connections.
In general, if the connection is lost after making some changes, most likely the reason is in them. If all else fails, reset your device to factory settings, remembering to back up important apps and data first.
Well, the most unpleasant thing that can happen is the failure of the Wi-Fi adapter. In this case, not only yours, but also other wireless networks will not be detected. There is already nothing to do, you have to carry your gadget to the service center.
In the wireless networks menu, you can configure everything related to the wireless connections of the Android device. And there can be a lot of them in modern communicators: cellular networks (3G / LTE), Wi-Fi, Bluetooth and NFC have already become a kind of “gentleman's set” of a top smartphone. We deliberately did not include A-GPS / GLONASS in this list, because in Android OS these connections are classified under the item “Location data”.
Bluetooth
Everything is arranged in a similar way in the Bluetooth menu. When you select this item, we immediately find ourselves in the list of all devices visible and connected using this interface, and the name of our smartphone is displayed in the first line. By clicking on it, the visibility modes are switched between “Show for nearby Bluetooth devices” and “Show only for connected devices”. Well, after clicking on the "menu" button, you can change the name of the phone, set the visibility timeout (including turning it off altogether) or open the received files - Android OS does not restrict users in the ability to transfer files using this protocol.
We will move on to the “Data transfer” item a little later, but for now, click on the “More” line. Here is the "flight" mode switch, which turns off all wireless connections, including the radio module (usually asked to turn it on on airplanes). Despite the immediate termination of all connections when this mode is selected, it remains possible to reconnect to a Wi-Fi network or a Bluetooth device when the cellular connection is turned off.
But most of all, the "Modem mode" item will be useful to us, thanks to which almost any smartphone running Android OS can distribute the Internet to nearby devices using Wi-Fi or Bluetooth. In the first case, the communicator acts as an access point, which is no different from other visible Wi-Fi networks. The user needs to set a name and password for it and tell them to whoever wants to connect their device to the Internet using your smartphone operating in the access point mode. The advantages of this mode are fast data transfer rates and a wide range of operation, and the main disadvantage is the high level of energy consumption (the smartphone battery is quickly discharged).
Another way is to do the same over Bluetooth. In this case, no configuration is even required: after enabling this function, it is enough to connect to a modem device from another device. This mode is much more energy efficient, but, at the same time, transfers data slower (however, this drawback is leveled when used on both Bluetooth 4.0 devices) and has a more limited range.
Limiting traffic
Now it's time to return to the “Data transfer” menu item, which we skipped last time, because when all wireless connections are already configured, it's time to think about traffic limiting, and Android, as we remember, is an “Internet-loving” OS. In this settings item, you can do the following: enable or disable data transmission over cellular networks, set alerts and limits on the use of EDGE / 3G / LTE and Wi-Fi traffic, and also find out which of the programs are the most "power hungry".
Of course, there are many special apps for Android that allow you to monitor network activity, but if you just want to be sure that you do not spend more traffic than your plan can afford, then standard tools are perfect for this. The central place on the “Data transfer” screen is occupied by a diagram showing the consumed traffic by day and two “sliders” for setting limits. The first one, yellow in color, is a warning; it shows the user a corresponding reminder in the notification panel when the specified level is reached. The second, red - limit, completely blocks the network activity of the communicator when it goes beyond the specified value. It must be enabled in advance by checking the “Set limit” item. The sliders are controlled in two ways: by moving your fingers or by clicking on the amount of allowed traffic and manually setting the value. By the way, we do not recommend setting exact limiting values, but leaving at least a couple of tens of megabytes “in stock”, since the traffic measured by the operator and the device may differ.
Quite often, many PC users who are somehow connected to the Internet, as well as gamers connecting to game portals, observe server connection errors. Now we will look at the question of what the operation timeout means. Moreover, several basic ways of solving this problem will be proposed.
Operation timeout - what is it?
So, an error appears on the monitor screen informing the user that the connection was interrupted, or rather, the connection timed out.
In principle, a timeout can be interpreted as a certain time period during which the system waits for the server to respond to its own sent request. In Windows systems, this parameter is set by default, and its value is written in the grid of the system registry of the current computer terminal settings in the SYSTEM subsection, where the Parameters subfolder is located in the subdirectories, where the time is specified in seconds. It is generally not recommended to change it.
Reasons for the error
There can be quite a few reasons when an operation timeout occurs. Let's highlight the most common situations. First of all, the main factor is an unstable Internet connection, when the connection is constantly interrupted, and the system cannot receive a complete response from the server to which the connection is currently being made.
In some cases, the operation timeout can be triggered when antivirus software is enabled or when the Windows firewall settings are incorrect. As you know, a firewall with default settings is capable of blocking a lot of web resources, considering them dangerous or containing potentially unwanted data. This is very common when connecting to servers in multiplayer online games.
Among other things, an operation timed out will time out the connection when using or misconfigured a proxy server. In this case, we are talking about the proxy settings in the system, and about the use of anonymous proxy servers, when the user, for whatever reason, wants to remain unrecognized, or, more simply, to hide the true IP address of his computer terminal. Let's consider several basic methods of correcting the situation without interfering with the system registry to set a higher timeout value.
Operation timeout: what to do? The easiest way to fix the situation
It is believed that the simplest way to get rid of is to simply close the unresponsive page and reopen it after ten minutes. Sometimes it may be necessary to close and restart the Internet browser itself (often, for some reason, such situations are observed in Google Chrome and other browsers based on it).
If this option does not help, and the message "Error: Operation timeout ..." appears again, you can apply a regular restart of your computer or laptop (or better, all routers such as routers or ADSL modems).
A solution to the problem of adding, say, a gaming site to the list of permissions (exceptions) of the antivirus and firewall can be quite effective, especially since in both cases it is not so difficult to do this in the settings.
Change proxy server settings
The situation with the proxy settings in the system is somewhat more complicated. Let's take standard Internet Explorer as an example. In the browser, you need to use the "Internet Options" section and the "Connections" tab.
Below there is a button "Network settings", after clicking on which you will enter the window for setting the parameters of the local network. Here you just need to uncheck (checkbox) the "Use a proxy server" line and save the changes (sometimes you can disable the proxy for local addresses).
But if the connection is made using a proxy, it is better to contact the provider to set the correct settings.
Fixing the system Hosts file
Now let's move on to a more complex method when an operation timeout can be triggered.
First, in the menu for displaying files and folders (in the standard "Explorer" this is the "Tools" menu with the line "Folder options") on the view tab, you must set the display of files.
After the above operation, you must open the Run menu and enter the command "notepad% windir% \ system32 \ drivers \ etc \ hosts" in the line (naturally, without quotes), the field of which will open the Hosts file in Notepad. Please note: there is a line “:: 1 localhost” at the bottom. In theory, it should be the last, so everything below it should be deleted, and then the file should be saved with its original name and location. Now all that remains is to restart the computer terminal. Then, usually, the error goes away.
Conclusion
That, in fact, is all about the triggered timeout. Of course, you can also use editing the system registry with setting a larger value for the server response timeout period, but only guarantees that all other resources will be loaded without problems, no one can give. In addition, as it is already clear, the pages themselves, if they are loaded, will take much longer. And this is not necessary for any user.
If you receive a message ( exactly when starting the program, or when connecting to hubs):
- "An attempt to establish a connection was unsuccessful because the required response was not received from another computer within the required time, or an already established connection was terminated due to an incorrect response from an already connected computer."
- "The requested address for its context is not correct"
POSSIBLE CAUSES (the first is the most probable):
- You do not have an established Internet connection or the program is preventing your firewall from connecting to the network.
- There is a problem in the local network (work in progress, etc.)
- You have a closed port on which the connection is made. For DC ++, this is usually TCP port 4111. Disable firewalls and antiviruses.
If you get the message: "The remote host has forcibly terminated the existing connection."- this means that the connection was physically interrupted. They cut the wire, turned off the hub, or simply lost packets in the line. Try reconnecting again. If it does not help, it may be a network problem, or your firewall is "naughty", see its logs. Also try disabling the firewall completely and see what happens (read more about firewalls below).
Problems downloading files or searching in DC ++
If everything swayed for you, and then suddenly stopped - remember what programs you installed during this period of time. Most likely, it is in them. But if you didn’t do anything with the computer, it’s just that nothing usually stops working.
If you put a file (or a list of files) to download, it appears at the bottom of the download list, and DC ++ writes Compound... (Connecting ...), size -1B and nothing happens. Or it writes "connection timeout". It means that something is wrong with you.
Likewise, if the file search does not work for you, then there are also problems with configuring DC ++ or other programs.
Check the possibility of downloading from passive users. If the download from them goes well, then most likely the problem is in your firewall. You need to open port 4000 via UDP.
IMPORTANT: For DC ++ to work properly in a 2KOM network, the following must be specified in your program settings:
- In the "Network interface for all connections" field, 0.0.0.0 must be specified)
- the port values must equal 4000
- connection type must be "Firewall with manual port forwarding", not Active!
- In field "External / WAN IP" your VPN or DHCP address must also be logged. This ( 144.76.94.14 ). If the following items are configured correctly, then this address will be entered automatically.
- On the first line under the button "Find IP Addresses" address must be specified http: //site/getip.php
- In the firewall, for your DC client, ports 4000 must be open over the TCP and UDP protocols. UDP is required for the search to work.
- Make sure in paragraph "Update IP at startup" costs check mark... Otherwise, you may have problems if your IP changes (for example, limit exhaustion, tariff change, etc.)
- In the settings of the "favorite" hub, the IP field must be empty
Detailed instructions for configuring client DC are here:
My search does not work
Read the previous answer ... Let me draw your attention to the fact that the search works over the UDP protocol, and the jump over TCP. Therefore, it is possible that in your firewall you allowed the DC client to work on TCP port 4000, and forgot to allow 4000 port on UDP ... so it does not work. There are no other options, so see your firewall.
Firewalls and firewalls
DC ++ is often blocked FireWall-ohm (Firewall, Firewall)- a program that protects your computer from network attacks, or antivirus software.
GENERAL TIP: If you have problems with downloads and searches, disable (or configure) firewalls, Windows firewall, and antiviruses and other network protection tools. How - read on.
If you do not have firewalls installed and the operating system is Windows XP SP2 or Vista: add DC ++ to the list of exclusions of the Windows firewall: when you first start the program (more precisely, when connecting to the hub) Windows will ask you whether to allow the connection or not. You must tell him "unblock".
Other "malicious" programs
Below is a list of programs that may affect how DC ++ works. If you have problems with DC ++ and one of them is installed --- disable it completely or uninstall (just to make sure that it is the case). If the demolition of the program does not help, then something else is interfering.
So, check if you have any of the following:
Antiviruses:
Kaspersky (Anti-Virus, AntiHacker, Internet Security), Eset NOD32, Symantec (Norton AntiVirus, Internet Security), Trend PC-Cillin, Avast, McAfee Antivirus.
FireWalls:
Outpost, WinGate, UserGate, WinProxy, WinRoute, ZoneAlarm, Comodo.
Most of these programs have the option of being completely disabled. To verify that they are causing problems in DC ++, disable them, restart DC ++, and check again. Adding DC ++ to the firewall exceptions list often helps.
To connect to the hub site should be open 4111 -th TCP port and 4000 ports to any addresses. Many firewalls provide the ability to open specific ports for DC ++ connections.
Routers (routers) and hardware firewalls
Owners of computers with motherboards on the nForce4 chipset in case of problems, we recommend disabling the hardware firewall built into the network card (nVidia Firewall).
If files larger than 4 GB are not downloaded
If you do not download large files (the program writes that there is no disk space), check that the disk being downloaded to has the NTFS file system, since FAT does not work with files over 2GB. If you have FAT32, then it makes sense to convert the disk to NTFS. This is done using the console command convert X: / FS: NTFS
Instead of X: This must be the letter of the drive you are converting. If it is too full, then no conversion is possible. After that, he will ask you to enter the disk label (you can see it in the disk properties):
The conversion is not instantaneous; it takes some time (usually a few minutes). In this case, all data on the disk is saved (do not turn off the power during conversion!)
Note: (for more advanced ones!) If you do not have enough space for conversion, but the partition on the disk is not the only one, and you need to resize the disk partitions, download or search the network for Acronis Disk Director Suite 10.0 (Off. Site) and run transformation with its help. How to use it, you will figure it out ... everything is simple there. Install, run, if it asks about "manual partition mode" and "automatic partition mode", select "manual", then it will show you your disks and partitions ... Right-click on the partition, there you can "convert" ("convert ") or resize ... Follow its instructions. Just in case, if you don't know English, take a dictionary and translate what she writes to you. The program is unsafe, it can threaten the entire disk and all data in no time, if you just stupidly click OK, or the button that is closer. ;-) By the way, this program can do almost anything with disks, from defragmentation to creating new partitions with any pre-specified file system.
Files are not moved from the folder with unfinished downloads
Sometimes it happens like this: the file is downloaded, but remains in the folder with unfinished downloads and a strange (distorted) name. Apparently this is a DC ++ bug. It appears when the Incomplete and Downloads folders are located on DIFFERENT partitions (for example, one on C:, the second on D:). In such cases, you can try to do the following: stop the download of this file (Ctrl + D, and remove it from the list if it still hangs there), and then forcibly rename the file. If, for example, this is a movie, then even the absence of 200-300 kb will not hurt. But usually, with such glitches, the file is still fully downloaded, just for some reason DC ++ cannot transfer it. But if after renaming the file does not open, it is better to delete it and re-download it.
Found and seemingly tested a solution to the problem: configure the incomplete folders and download folders so that they refer to the SAME disk partition. You can install them on the same directory for simplicity.
Problems with access to the HUB
I can't go to the hub, writes ........., *** Connection timeout
Either the hub is temporarily disabled, or your mesh is broken at the moment, or you have not allowed the DS ++ client in the Firewall.
... Connection refused by target machine
a) Your firewall is blocking the DS client. Configure or uninstall it (be sure to restart your computer after uninstalling)
b) The server where the hub is located is working, but the Hub itself is not turned on.
... You are still temporary banned for another 00:05:00
You have been kicked / banned - the hub will say, the hop is left until "auto-forgiveness"
... Bad nickname. Nickname already in use
Glitch DS ++. It means that your name is already used on the Hub. Most likely this is your "shadow". Just change your nickname to "VashNik1" and enter. Over time, the "shadow" will disappear. (it happens if you turned off
... Turn on your tags!
Your client is different from the original DS ++, so the Hub may not let him in. In the client settings, find "emulate (pretend to be) a standard DS ++ client"
A message appears like "Active Search: Your ip is not 172.30.xxx.xx it is 144.76.94.14 bye bye." and disconnects.
This message appears when your client sends a search request in active mode, and he reports his IP in the request. And if this IP is different from the one under which you actually connect to the hub, then you will receive this message. To prevent this from happening, make sure: After making the changes, restart the client, there should be no problem.DC ++ and Windows Vista
Since Windows Vista introduced a mechanism to protect files in the "Program Files" directories, DC ++ clients cannot change their config to work correctly. This causes freezes and glitches.
For correct operation, run the client with administrator privileges:
Right click on the client shortcut, select properties:
Go to the compatibility tab and check the "Run as administrator" box:
Brief instructions on the process of downloading films from film.2kom.ru
In the window that appears, you can choose:
- Start searching for this file
- Add this file to the queue
If you select "Start searching for this file", then a search will be made for users who are currently connected to the server. But since the file may be in the possession of users who are not currently connected to the server, we recommend that you select "Add this file to the queue". Then the file will be added to your queue and the download will start immediately as soon as the user who has this file appears on the network.
The 504 Gateway Timeout error is an HTTP status code that means that one server did not receive a timely response from another server it contacted when trying to load a web page or make a browser request. It can occur along with 502 Bad Gateway.
In other words, the 504 error indicates that the server hosting the site and the computer on which the 504 error pops up does not have a stable, fast enough connection to the Internet.
How you can see the 504 error
Individual sites are allowed to customize the display of the Gateway Timeout error. Here are some common ways to display this error:
504 Gateway Timeout HTTP 504 504 ERROR Gateway Timeout (504) HTTP Error 504 - Gateway Timeout Gateway Timeout Error
The 504 Gateway Timeout error appears inside the browser window like a normal web page. It might have familiar site headers and footers and a nice English message. Also, a similar error can be displayed on a completely white page with a large number 504 at the top. They are the same message no matter how the site shows it to you.
Remember that 504 Gateway Timeout and 502 Bad Gateway ngin errors can appear on any browser, operating system, and on any device.
Causes of Error 504 Gateway Timeout
In most cases, a 504 Gateway Timeout error means that any server that issues a "timeout", "crashed" or is not working properly.
Since this error usually occurs between servers on the internet, it probably isn't related to your computer, device, or internet connection.
How to fix error 504 Gateway Timeout
- Reload the webpage by pressing the refresh / reload button in F5 or by repeating the URL from the address bar.
Although the 504 Gateway Timeout and the 502 Bad Gateway error are reporting an error beyond your control, the problem may be temporary. Just reload the page - it's quick and easy.
- Restart all network devices. Temporary problems with your modem, router, switches, or other networking equipment can cause a 504 Gateway Timeout error. A simple restart of these devices can help.
Hint: While the order in which these devices are turned off is not important, the order in which they are turned on is, on the contrary, very important.
- Check your proxy settings in your browser or app. Make sure they are correct. Incorrect proxy settings can cause 504 error.
Clue . See Proxy.org for an updated, verified list of proxy servers that you can use.
Note. Most computers do not have proxy settings, so if your settings are empty, skip this step.
- Change the DNS server. Perhaps the 504 Gateway Timeout error you are seeing is caused by an issue with the DNS server you are using.
Note. The DNS server in use now is probably automatically assigned by your ISP. Fortunately, there are other DNS servers available for use that you can choose from.
Clue . If not all network devices receive the HTTP 504 or 502 error Bad Gateway, but they are all on the same network, changing the DNS server will not work. If this is similar to your situation, move on to the next idea.
- If there are no changes, refer to the site. This is the only thing you can do. Chances are good that the site admins are already working to fix the root cause of the 504 Gateway Timeout error.
Most sites have social media accounts that they use for support. And some even have phone numbers and email addresses.
Clue . If the site starts to seem like it is throwing a 504 error for everyone, check Twitter for real-time information about the site being unavailable. The best way to do this is to find #websitedown on Twitter. For example, if Facebook might not be available, search for the #facebookdown tag.
- Check with your internet service provider. Most likely, after the troubleshooting described above, the 504 Gateway Timeout popping up is a problem caused by network problems that your ISP is responsible for.
- Come back later. At this point, you have exhausted all options and the 504 Gateway Timeout error is being fixed by the site administrator or ISP.
Check the site regularly. No doubt it will start working again.
Fixing the 504 error on your own website
In most cases, this is not your fault, but also not the fault of the users of your resource. Start by verifying that the server can properly provide access to all domains your applications require access to.
Large amounts of traffic can cause your server to generate a 504 error. Although a 503 or 502 Bad Gateway error will be more likely.
Specifically in WordPress, the 504: Gateway Timeout message sometimes occurs due to corrupted databases. Install WP-DBManager and try using the "Rebuild DB" function and then " Optimize DB". See if this helps.
Make sure your HTACCESS file is correct. Especially if you've just reinstalled WordPress.
Contact hosting technical support. Perhaps the 504 error your site is returning is due to an issue on their end that they need to resolve.
More ways to see a 504 error
Gateway Timeout error when received in Windows Update generates error code 0x80244023 or message WU_E_PT_HTTP_STATUS_GATEWAY_TIMEOUT.
In Windows-based programs that initially access the internet, a 504 error may appear in a small dialog box or window with the HTTP_STATUS_GATEWAY_TIMEOUT error and / or the message The request was timed out waiting for a gateway (request timed out for gateway).
A less common 504 error is Gateway Time-out: The proxy server did not receive a timely response from the upstream server (the proxy server did not receive a timely response from the upstream server), but troubleshooting (above) continues.
