Today I want to talk about one common error that appears among users of the Google Chrome browser and all the like, working on its own engine. It manifests itself in the fact that the Internet browser writes: "Unable to access the site", and below is a detailed description of the problem:
At the same time, there is no dependence on the operating system - the error can appear both in the good old Windows 7, and in the G8, and even in Windows 10.
Main reasons her appearances are as follows:
- The site is really unavailable
- Problems with DNS or hosts file
- Proxy settings
- The address is blocked by the security system
- Other
Now we will consider each of them in more detail and tell you about ways to remedy the situation. But before moving on to finding a solution, let's do this. First, it is advisable to check whether there are definitely no problems with Internet access. The easiest way to do this is when you are connected through a router - try to access the global web through some other device: tablet, smartphone, laptop, etc. If there are no problems with access, try accessing the desired site from this test device. If the resource is available from it, but not from the computer, immediately start with the second reason and further.
In the case when nothing else is at hand, the ping test utility will come to the rescue. Launch the Windows command line and type the command:
Ping 8.8.8.8
press the Enter key and look at the result. It should look something like this when there are no problems with access:
If in response you receive the message "Network node is unavailable", then first you need to deal with your Internet channel.
1. The website is not responding
This is the simplest case and his solution is nowhere simpler. The fact is that although for the operation of portals and sites on the Internet, hosters use reliable equipment, and system administrators vigilantly monitor the trouble-free operation of servers - anyway, sooner or later, failures do occur. And then you have to wait a little while the specialists restore its work. This is especially true for unpretentious pages on cheap hosting. Bigger and better-known sites are supported more thoroughly and problems are fixed much faster.
The browser may display the message "Unable to access the site" even if a mistake was made when writing its address. In this case, usually the description indicates the code ERR_NAME_NOT_RESOLVED, which in translation means "could not recognize the name of the site."
2. Problems on the computer with DNS or the hosts file
Unfortunately, as my experience tells me, this is the most common reason. let's check which DNS servers are registered in the system. If non-working addresses are indicated there, then the Internet on the computer will not work, constantly displaying the error "Unable to access the site." Therefore, to check, go to the Control Panel, find the Network and Sharing Center there. There, in the menu on the left, we find the item "Changes to adapter parameters" and click on it. Thus, you will be taken to the list of Windows network connections.
We find the local network connection through which the computer has access to the global web. Click on it with the right mouse button and select "Properties". In the window that appears, double-click on the line "IP protocol version 4 (TCP / IPv4)". Another window should open, like this:
We tick the box "Use the following DNS server addresses" and indicate as preferred one of the public Google servers - 8.8.8.8 ... As an Alternative, you can register the IP of your router (if any), or the server from Yandex - 77.88.8.8 ... Click the "OK" button to apply the settings.
It also does not interfere with checking if there are any unnecessary entries in the file - this is a system file that has a higher priority in the system than a request to the DNS. That is why all sorts of malicious programs very often use it and write their data there. We launch the text editor Notepad with Administrator rights and go to the folder C: \ Windows \ System32 \ drivers \ etc... In it we find and open the hosts file. By default, it should look like this:
There shouldn't be any other entries below! If there is something - feel free to delete it.
3. Proxy settings
Very often, problems with websites, and indeed with access to the Internet, arise after one of the children or relatives climbed in the parameters and for some reason enabled the use of the Proxy server. Needless to say, after that, no resource on the network will be able to enter and the browser will write "Unable to access the site." Therefore, we open the Windows 10 settings, find the "Network and Internet" section and select the "Proxy" item:
We find the switch "Use a proxy server" and move it to the "Off" position.
4. Security system
Today, working on the Internet without a normal antivirus and firewall (aka firewall) is akin to dancing in a minefield: lucky, unlucky. But sometimes the computer's security system is too diligent, blocking the necessary addresses. To exclude this option - try to temporarily suspend or disable the firewall and antivirus altogether.
If after that access to the site is restored, then you either need to add it to the list of exclusions, or take a serious look at it - perhaps it is phishing and is intended to deceive the user and steal information.
5. Other reasons
This includes all those options for the development of events that are least often encountered in practice, but still have a place to be.
- One of these is problems with the Windows DNS client. Let's check if it works and try to restart it. Press the Start button with the right mouse button and select the "Computer Management" menu item. The following snap-in will open:
In it you need to find the section "Services and Applications" >> "Services". In the list of system services, we find the line DNS client and look at its status. If the service is running, we will try to restart it. To do this, select and in the menu on the left click on the first link "Restart service".
- Sometimes the reason that the Google Chrome browser writes "Cannot access the site" is the failure of Windows network services. To fix it, you need to have Administrator rights and run the following commands.
Clearing the DNS cache:
Reset and update the IP address:
Ipconfig / release ipconfig / renew
Resetting static routing rules:
Route -f
After that, you need to restart your computer and check if the desired site is now available.
- Also, do not forget that access to can be closed from the side of the site itself. You can check this with the help of special anonymizeres. For example: Anonymouse.org. If the required address is opened through it, then most likely you are hooked or your IP address is specifically prohibited in the firewall parameters of the web resource.
Stable and fast access to the World Wide Web is not a guarantee that you will be able to freely visit your favorite Internet resources. The error "Unable to establish a connection to the site" often appears at the most unexpected moment.
The essence of the error is that sites stop opening on the computer or on all devices connected to the same router, although there is a connection to the Internet. Let's talk about what could be the cause, how to identify the culprit and what measures to take to eliminate it.
No access to all sites
Website opening errors occur for many reasons. The first group includes situations when the browser cannot access any Internet resource. This group is more common and its reasons are more varied than in cases when only certain sites do not open.
Reasons for lack of access
- Failure of the network settings of the PC or router (can be introduced by the user or software, including malware).
- Damage to the components of the OS network subsystem (it can be the result of user actions, operating system failure, infection and deletion of files of this structure with a malicious program, blocking or removal by antivirus).
- Incorrect settings of the firewall (firewall) or parental controls (the browser is denied access to the Internet).
- Very slow or disconnected Internet connection.
- Connecting to the network through malfunctioning or low-speed proxy servers and VPN.
- Incorrect settings or browser crash (including installation of "crooked" extensions and custom scripts).
- Activities of malicious programs (except for changing network parameters and components, the virus can inconsequentially block the loading of sites).
- Problems on the ISP side.
How to find the culprit
An analysis of the events that preceded it will help you to think about the culprit of the failure.
If before the error occurred:
- any actions with the router: replacement, repair, firmware update, change of settings, etc .;
- changing the parameters of the network connection on the PC (for example, new DNS addresses were registered);
- installing or removing programs that interact with network structures (Internet accelerators, traffic analyzers, 3G / 4G modem applications, etc.);
- manual or software cleaning of the system from garbage, optimization, removal of "viruses" using antivirus utilities, editing the registry, changing group policies,
the most likely cause is incorrect network settings or damaged network components.
If the following occurred before the failure:
- installing or removing a firewall or antivirus software with a built-in firewall;
- changing firewall (firewall) settings;
- installing or reconfiguring parental controls;
- the appearance of messages about the insecurity of the network connection with a proposal to strengthen the protection,
the culprit is most likely an antivirus, firewall (firewall), or parental control tool.
If the event is accompanied by:
- spontaneously pop-up advertising;
- violation of system functions;
- errors during normal operations (opening a folder, copying, etc.), which were not there before;
- antivirus program alerts;
- loss of access to electronic wallets and Internet accounts that you used on this PC;
- other unusual phenomena that have not been observed before,
the reason is most likely a viral infection.
What to do next
The troubleshooting procedures below cover all of these causes. If you have an idea of the specific culprit of the problem, you can only follow the steps that are appropriate for your case. If the previous one does not help, move on to the next one.
- Reboot your router. Check your Internet connection settings, black and white lists of sites, DNS addresses. If you do not know the specified DNS, write down the addresses of your provider or Google instead.
- Check the network connection settings on your PC. The default gateway must be specified. DNS server addresses (if not automatically assigned) must match the IP of the default gateway, belong to your ISP, or be public.
- If you are using a VPN or proxy to access the global network, disable them.
- Make sure your Internet connection is stable and your connection speed is sufficient, for example, using this service.
- Reset your network settings. To do this, run the system application " Parameters", Go to" Network and Internet"And in the right side of the window, click the button" Network reset". Next click " Reset now". This action will reinstall the Ethernet and WLAN adapters and restore all network components to their original settings. After performing the reset operation, the computer will restart.
- Temporarily disable firewall or firewall and parental controls, if using. To disable the Windows 10 firewall, run " Parameters", Open" Updates and security» – « Windows Security". On the right, click " Firewall and network protection". In the Defender Security Center window that opens next, click the connection marked as " Active". Next, move the slider of the firewall to the " Switched off».
- Check if the problem occurs in other browsers. If it is present in only one, most likely the reason lies within the browser itself. Check its Internet connection settings (if you do not use proxy and VPN, but they are registered in the browser settings, delete these entries), disable extensions and custom scripts,. If all else fails, export your bookmarks and reinstall your browser.
- To exclude the active influence of running programs (including malware), with network support. If access to the sites is restored, the reason is in the programs. It remains to find which one. However, if changes made to the system cause a failure, this will not help to identify and remove them, since they remain in effect even without the presence of the programs that created them. Use the following method to deal with changes.
- for the day when sites opened without errors.
- Scan your disks with an antivirus.
- If the problem occurs on all devices connected to your Internet provider's network, and vice versa, does not occur when connecting to another, call the provider's support service and follow the recommendations of the consultants.
No access to individual sites
Causes
The lack of access to some sites can be caused by most of the reasons listed above. But here there is one caveat - you can make an assumption about the culprit of the failure on the topic of inaccessible content.
For instance:
- There is no access to torrent trackers and other similar resources prohibited in your country. The reason is blocking by the provider or a higher-level controlling organization. According to the rules, a stub page with a formidable inscription “ Site blocked by decision ...", But sometimes the error" Unable to connect to the site". By the way, sometimes innocent resources, such as Google services, fall under the distribution.
- Pages of adult topics, VK and your favorite online game do not open. The likely cause is parental control, firewall, or DNS blocking with content filtering. Sometimes in such cases, more sophisticated methods are used - blocking through the Hosts file and so on, which I will discuss later.
- Social networks, mail and antivirus resources, search engines do not open. This picture is typical for viral infection.
What to do
In case of unavailability of individual sites, the same diagnostic methods and solutions are used that are used for problems with access to all. But with the amendment: - your allies, not enemies.
And separately about the blocking methods used by malicious programs. Removing the malware is often not enough to unblock access to a website: along with it, you need to remove the changes it made to the system.
- Hosts file
In a simple way, the file % windir% \ System32 \ drivers \ etc \ Hosts Is a local DNS service. It serves to tell the computer which IP addresses to look for specific sites, the names of which are listed in this file. If you write in Hosts that the site ABC.com is located at 127.0.0.1, then the computer will look for it not on the Internet, but on its disks. And since it won't find it, it won't be able to open it in the browser.
By the way, viruses sometimes hide the entries that they have made in Hosts from the user. About the methods of concealment.
Hosts is a text file with no extension. To remove a blocking entry, open it in notepad or a replacement notepad program and simply delete unnecessary lines. If after editing the file is saved with the extension .txt, remove the extension.
There is a class of malware capable of rewriting DNS addresses in the network settings of a PC and router. If you notice unfamiliar DNS on your devices, write down the provider's or public addresses instead.
- Static routes
A static (persistent) route is a hard-coded path for web traffic to travel from one host (for example, your computer) to another (a site on the Internet). Accordingly, if the route is set incorrectly, the site will not open. The work of this mechanism is described in more detail in the above.
To find out if your PC has persistent routes, follow the instruction in the command line route print
To delete all routes follow another instruction: route -f
- Scheduled tasks
A scheduled task is some kind of instruction that the operating system executes on a schedule or when an event occurs (for example, after Windows starts up). Such tasks can be created by both users (via the Task Scheduler) and programs installed on the PC.
Scheduled tasks are stored in folders % windir% \ tasks and % windir% \ system32 \ tasks as text files: one task - one file. A file created by a malware is usually easy to identify by a meaningless name made up of a set of numbers and letters, such as sgjed4jlui.job. In addition, the date of its creation, as a rule, coincides with the date of the problem with opening sites.
Before deleting suspicious tasks, it is advisable to back them up - in case of a possible error.
- Malicious proxies
Proxy servers are intermediate nodes that pass the network traffic of a computer (router) through themselves before accessing the World Wide Web and back. In addition to useful tasks, such as protecting traffic or masking IP, they can be used by cybercriminals to redirect the user of an infected machine to phishing web pages, as well as to block access to individual sites.
Proxy servers (if used on a PC) are registered in the system registry, namely, in the sections HKLM \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Internet Settings and HKCU \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Internet Settings
The parameter is called ProxyServer.
To remove a parameter from the registry, right-click on it and select " Delete". The changes will take effect after you restart your computer.
In the process of working on the Internet, a number of users may be faced with the impossibility of entering any site. This problem can affect all sites, or some of them, and is linked by the message " Can't access the site", As well as data on any specific error (ERR_NAME_NOT_RESOLVED, ERR_CONNECTION_ABORTED). In this article I will tell you what kind of error occurred when accessing the site, I will describe its reasons, and also explain how to fix the error "Cannot find the DNS address of the server" on your PC.
Screenshot of the error "Unable to access the site"
Unable to access the site - symptomatology
As mentioned above, the occurrence of this error can have several reasons, which are often mentioned in its text. Among the popular ones are the impossibility of finding the server's DNS address, the impossibility of resolving the server's DNS address, the waiting time from the site has been exceeded, the page is temporarily unavailable, the connection was dropped, and a number of others.
After the error "Unable to find the DNS address of the server" appears, the required page of the site usually does not open. At the same time, in some cases, various messengers and other programs that work with the Internet - skype, icq, paltalk and a number of others work without any problems.
Reasons for the lack of access to the site
So why can't you login to the site? The current problematic environment may have the following reasons:
- Accidental computer failure, this is not as rare as it might seem;
- Unstable internet connection;
- Browser functionality crash;
- Failure in the DNS settings on the user's PC (including failure of the DNS service);
- Problems in the work of the provider or blocking by the provider of the work of any site;
- Involved "parental control" in the system;
- Problems in the operation of the router;
- Blocking the connection by antivirus or firewall for specific reasons;
- The activity of virus programs;
- The work of any add-ons to the browser, blocking access to the site.

What to do if the error "Unable to find the DNS address of the server" appears
One of the most common variations of the login error is the problem with the inability to find the DNS address of the server. At the same time, this dysfunction may appear both due to some problems with the DNS service on the computer, and due to problems with the DNS settings received from your provider. To fix the error "Unable to find the DNS address of the server", in addition to the above general tips, you need to do the following:
- Clear the DNS resolver cache... Click on the "Start" button, enter "Command Prompt" in the search bar, right-click on the result just above and select "Run as administrator". At the command prompt, enter ipconfig / flushdns and press enter;
Conclusion
In this material, I analyzed the complex of reasons for the problem "Cannot access the site", and also proposed various options for its solution. As the reader could see, this dysfunction can be caused by many reasons, and the tools for getting rid of it will be a set of tips I described above. For the most part, it is the problem with DNS that causes the described dysfunction, therefore I advise you to pay special attention to the mechanism for solving this problem discussed above.
