In this article I will tell you about different solutions that can come in handy in the event that your browser stops opening pages. At the same time, the Internet is there, and it works. Programs such as Skype, various torrent clients and the like continue to work and go online. And sites don't open in all browsers. When you try to open a page, it first takes a long time to load, and then an error appears that the page cannot be accessed, and the browser could not open it. The error text itself may differ depending on the browser.
In Opera and Chrome, for example, the error: "No internet connection", or "Cannot access the site". V Mozilla browser: "Server not found", in Yandex Browser: "Unable to establish a connection to the site", and in Microsoft Edge (which is in Windows 10): "Failed to open this page."
It doesn't matter what browser you have, in any case, the pages will not open. But here the moment is important that the Internet is working on the computer. There is no yellow exclamation mark next to the cable or Wi-Fi icon. If it is, then this is another problem, and there are other solutions. If you have such a case, then write in the comments, I will give links to instructions. Perhaps you have the Internet connected via a router or modem, in which case the sites may not open on all devices. I will write about this below.
Well, there are also situations when only some sites do not open on the computer. These are usually sites search engines, or social networks: Odnoklassniki, Vkontakte, Facebook, etc. In this case, the solutions I will discuss below should correct this situation.
And one more thing: no matter what Windows version installed on your computer, just like a browser. I will show on Windows example 10. In Windows 7 and Windows 8, the solutions are the same. If the actions are different somewhere, I will write about it.
Why won't browsers open sites? How to fix?
You could immediately put heavy artillery into battle, and talk about difficult decisions (although often the most effective), but as practice shows, it is better to first apply several simple actions, which also often help to get rid of this or that problem.
- Restarting your computer, router, modem is the first thing. Did not help? Go ahead.
- If you have the Internet through a router, and on all devices, pages do not open in all browsers, then it makes sense to call the provider's support and report the problem. It is possible that they have some kind of hardware failure, and because of problems with DNS servers, sites do not open.
- If the problem is with one device, or the Internet is connected directly to the computer, then it makes sense to disable the antivirus for a while.
- Very rarely, the problem appears suddenly. Think, browsers may have stopped loading sites after changing some settings, treating viruses, installing programs, antiviruses, etc. This is very important. After all, you can always undo some changes, or remove installed programs.
- If possible, connect to the Internet another device, another computer, and try to go to some site. If everything opens, then you can eliminate the problem on the provider's side, in the router, or modem.
If the tips described above did not help, then there is no need to get upset, I have a few more good decisions... First, I will tell you about the most effective solutions based on my own experience and feedback in the comments to other articles.
DNS problem is the most common cause
It is precisely because of problems with DNS addresses that it is most often not possible to access sites. Skype and other programs can still work without problems. In this case, the browser may say that the DNS server could not be found, or something like that. What should be done:
- Change DNS in the connection properties on the computer. I suggest registering DNS from Google. If the problem is on all devices, then DNS can be registered in the router settings, or separately on mobile devices.
- Reset the DNS cache. What is it like additional way... It is enough to open the command line as administrator, run the command ipconfig / flushdns, and restart your computer.
I wrote about this in more detail in the article:. Everything is simple there. First, go to network connections.
After reboot (or even without it) everything should work. How to change DNS in the router settings, I showed in the article, the link to which I gave above.
We check the properties of the browser (educator), disable the proxy
You need to check some settings in the properties of the educator. Is there a script set there automatic tuning, and whether proxies are installed. Since the parameters are specified in the properties of the educator, they apply to all browsers. And different viruses and malware it is not uncommon to make changes to these settings, after which the sites cease to come off.
Go to the control panel. Switch the view to Large Icons, find and open "Educator Properties"... This is in Windows 7 and XP. If you have Windows 10, or 8, then there this item is called "Browser properties"... It can be found and run through a search.
Go to the "Connections" tab, and click on the "Network Settings" button. Another window will open. Check that the settings match those in the screenshot below.
Proxies and autoconfiguration scripts must be disabled. If any parameters were set there, then after turning them off, everything should work.
Solution in Windows Registry
Press the key combination Win + R, in the "Run" window enter the command regedit and click "Ok". The Registry Editor will open. Go to the section:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Windows \
There will be different options in the window on the left. We are interested in the parameter AppInit_DLLs... The value of this parameter must be empty. If you have something spelled out there, then double tap on the AppInit_DLLs parameter, open it, delete everything from the "Value" line, and click Ok.
HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Windows \
If you do not find the required parameter in this section, then it's okay. Just restart your computer.
Clearing the routing table, resetting the TCP / IP protocol
You can try to clear everything network settings... If you have Windows 10, then this can be done through the options by pressing just one button. I wrote about this in more detail in the article:. Or do everything as shown below.
Important! If you have a configured connection to an ISP, or to access the Internet you set some statically IP settings, then after resetting the settings, you will most likely need to reconfigure the connection. If you are not sure if you can do this, then it is better not to do a reset.
First, clear the routing table. Run Command Prompt as Administrator and run the following command ( copy it to the command line and press Enter):
Restart your computer and check the result.
If this does not help, then start the command line again, and run these two commands in turn:
netsh winsock reset
netsh int ip reset
After that, you also need to restart your computer. Then open your browser and try to open some page. If sites still won't open, try the other guidelines in this article.
Websites do not open because of the hosts file
It makes sense to check the contents of the hosts file. Especially if you have a problem opening only certain websites. For example: vk.com, ok.ru, etc. If your browser does not open a single page, then there is hardly a problem in the hosts file.
In File Explorer, navigate to C: \ Windows \ System32 \ drivers \ etc. You can just copy this path and paste it into the explorer. Next open hosts file through notepad.
It should look something like this (I have Windows 10):
If you have any other lines there that you did not write yourself, then you can try to delete them and save the hosts file.
Or just search on the Internet standard file hosts, copy the content to your file and save. V Windows 7, 8 and 10 file content will look the same as in the screenshot above.
Viruses and malware - the cause of the error "Unable to access the site"
If you have tried different solutions, but the sites still do not want to open in browsers, an error appears that the page is inaccessible, then it is possible that your computer is infected with some kind of virus, or all this is the trick of some kind of malicious program. Especially if you don't have antivirus installed on your computer.
It is not uncommon for malicious programs to change some parameters, network settings, browser settings. As a result, sites stop opening, and the Internet continues to work.
I recommend downloading one of the utilities that are designed to find and remove malware and scan your computer. Also install an antivirus (if not available), and run a computer scan. Among the anti-virus utilities, I would recommend: AdwCleaner, HitmanPro, Dr.Web CureIt !, Zemana AntiMalware, Junkware Removal Tool.
These utilities can be downloaded from the Internet without any problems. They are very easy to use. Most are in Russian.
A few more points:
- There is information that pages may not load due to Avast antivirus. Everything starts working only after disconnecting, or complete removal antivirus.
- If after applying some solution everything worked, but after a while the problem returned, then most likely this indicates that the computer is infected, and the virus registers some parameters back, due to which the problem returns.
- Check if the time and date are set correctly on your computer.

There are several reasons why the browser stops loading pages when the Internet is available properly. In this case, the type of device (computer or laptop), the type of Internet connection (cable or Wi-Fi), the type of operating system and the type of browser do not matter. An attempt to open any page leads to the fact that it takes a long time to load, after which it appears error message.
The text of the message itself may differ depending on the type of browser and may help in identifying the error. One of them is the problem with DNS address when it is not specified in the network settings, not available or specified incorrectly. Another common error is problems with the hosts file, proxy server or registry, and malware.
How to fix the error
The simplest thing to do first is reload computer, modem and router. Sometimes, if hardware failure is the cause, it can help.
At problem withDNS first of all, you need to ping a public DNS server, for example Google. If the host is not found during the ping test, then the reason is DNS unavailability. To solve the problem, it is recommended to register DNS from Google. You need to go to network connections, select your type of Internet connection, click " Properties"And register DNS Google: 8.8.8.8
... After rebooting, everything should work. 
If the problems are related to the registry, you need to go to the registry editor and select the item in its sections NKEY_
LOCAL_
MACHINE\
SOFTWARE\
Microsoft\
WindowsNT\
CurrentVersion\
Windows... Then a list of parameters will appear, among which you need to find Applnit_
DLLs... You should check its value, if it is not empty and the path to a file with the dll extension is written in it, then it must be reset. After that, the same actions must be done with the parameter HKEY_
CURRENT_
USER and restart your computer. 
The cause can be malware and software, which are often not even detected. antivirus software... In such a situation, you need to use special tools with which you need to scan your computer. These include such utilities: AdwCleaner, Dr.WebCureit, JunkwareRemovalTool and others. 
If lost proxy settings, you need to check that there is nothing superfluous in its parameters. To do this, go to the properties of the browser and click the tab " Network configuration"In the Connections section. The checkbox should be on a single line: “ Automatic parameter detection". It should be noted that this will not always help, because in some cases the proxy must be set manually. 
Filehosts usually does not allow opening some sites, while some portals open normally. To resolve the situation, you need to go to the folder: With:\Windows\ System32\ drivers\ etc and open the hosts file. Inside it is text ending with the line 127.0.0.1 localhost. If further there are any lines with ip addresses that the user did not register, they need to be deleted and the system rebooted.
You can remove all lines from the file if necessary. This will not affect the performance of the system in any way, but some hacks can fly off if the cracks prescribed a prohibition on updating some programs in this files. 
In this article we will try to figure out for what reason and why the browser stops loading pages and visiting different sites. Despite the fact that the Internet continues to work normally, judging by the connection status on the notification panel. V in this case it doesn't matter if you have a PC or a laptop. Installed on it Windows 10, Windows 8, or Windows 7. And it doesn't even matter how you connect to the Internet: by cable directly, or through a Wi-Fi router.
If there is a red cross or yellow exclamation mark near the icon, then the browser does not load the pages due to the lack of an Internet connection. And we need to solve this problem. First of all, we restart the computer and the router. (if you have a connection through it)... You may also find these articles useful:
When the internet connected and working, then the icon should be like this:
Usually, when the Internet is there but the sites are not loading, then programs such as Skype do not lose their connection to the Internet. Pay attention to this. And if your internet works (connection status as in the screenshot above), but does not go to sites through different browsers, then try to apply the recommendations, which I will write about below in this article. And further:
- If you have a connection through a router, then check if the sites are loaded on other devices. If not, then restart your router. You can also connect the Internet directly to your computer and try to go to some site. Perhaps this problem appeared due to the fault of the provider.
- In the event that the problem is only on one computer, then it is important to remember when and after which it appeared. For example, after installing a program.
- Restart your computer and run diagnostics Windows networks... You need to click on the connection icon right click mouse and select "Diagnose problems". You can write about the results in the comments.
- Try to go to different pages. Perhaps the problem is in one specific site. Also try different browsers.
The problem is clear, let's move on to solutions.
If the browser does not load pages, the first thing to do is change the DNS
This is the most popular and most working solution to this problem. Almost always, it is because of problems with DNS that sites do not load when the Internet is working. And in such cases, I recommend registering DNS from Google. This is not at all difficult to do.
You need to go to network connections. Do it in a way convenient for you. You can press the keyboard shortcut Win + R, enter the command ncpa.cpl and click Ok.
Right-click on the connection through which you are connected to the Internet and select "Properties".
In the new window, select "IP version 4 (TCP / IPv4)" and click on the "Properties" button.
Like the screenshot below.
Everything should work right away. If not, try restarting your computer again.
More information on this topic in the article:.
ipconfig / flushdns - flush DNS cache
Run Command Prompt as Administrator and run ipconfig / flushdns. DNS cache will be reset and the problem may be corrected.
It should look something like this:
After that, it is advisable to reboot.
How proxy settings can affect page loading in a browser
If some program, possibly even malicious, or we change the proxy server settings ourselves, this may cause this problem. You need to check that there are no unnecessary settings in the proxy server parameters.
In Control Panel, find and open "Educator Properties". If you have Windows 10 installed, then this item will be called "Internet Options". You can type this phrase in the search, it will be faster.
On the "Connections" tab, click on the "Network Settings" button. Check that the settings are like mine in the screenshot below.
If everything is fine with you, then move on to the next solution.
Reset network settings
In Windows 7, Windows 8 (and in the top ten), you can reset the network parameters with separate commands that you need to execute in turn in command line running as administrator.
ipconfig / flushdns
ipconfig / registerdns
ipconfig / release
We execute the commands in turn.
Remember to restart your computer.
Installed Avast?
If your computer has Avast antivirus, then there is a high probability that the browser cannot load sites precisely because of it. There are comments in the comments that reinstalling the antivirus solves this problem.
Try uninstalling Avast first. If the internet works, you can install it back.
Nothing helped, are there any more options?
Check your computer for viruses. There are many good, free antivirus utilities out there. If you have an antivirus installed, then run a computer scan.
You can also try to temporarily disable the antivirus. Maybe he changed some network settings, and the pages in the browser stopped opening.
Think, maybe the problem appeared after installing or uninstalling a program. Or changing some parameters. So you can find out at least an approximate cause of these problems.
If I remember something else, or learn something new about this problem, then I will definitely update the article. You also share your experience in the comments, write about working solutions. You can leave your questions.
