Anonymity, free surfing and accessible exchange of information are the main tenets on which the creators of the Internet relied. However, with the development of society, people realized that not all information can be shown. Some data can pose a threat not only to individuals, but also to entire states. Therefore, in the modern world, blocking sites and services has become commonplace. The problem is that sometimes completely safe sites or just social networks are blocked. And a proxy server can help in accessing prohibited resources.
What is a proxy server and what functions does it perform
A proxy server is an intermediate link between the user and the rest of the global web. The principle of its work is that people using the service can freely work on the Internet. At the same time, standard protocols for fixing and blocking IP do not work, since surfing the network occurs remotely using Proxy. This way you can remain anonymous and receive content that is not available at the provider or country level.
Using a proxy server, you can maintain anonymity on the network
Connecting and configuring a proxy server in the operating system
There are two ways to connect to the proxy server:
- directly in the browser (then requests from this program will go through an anonymous server);
- connect the entire computer (in this case, all traffic will go through the Proxy).
How to connect is everyone's business, but it is worth remembering that the resources of services are not unlimited, therefore, you can almost always observe a decrease in the speed of traffic on the Internet when using a proxy.
On Windows 7-10
On Windows, Proxy settings are located in the properties of the Internet Explorer browser.
- Press the key combination Win + R on the keyboard and enter control in the "Run" field, then press Enter.
Through the executing program, open the "Control Panel"
- The "Control Panel" will open. Change the view to icons, then click on the "Browser Properties" element.
Among the elements of the "Control Panel" select "Browser Properties"
- Immediately go to the "Connections" tab, click on the "Network Settings" button.
Go to the "Connections" tab and click "Network Settings"
- The settings window will open, in it we put a tick opposite the item "Use a proxy server ...". Next, the form for the IP address and connection port will become active. We enter the necessary data and save the changes by clicking OK in all open windows.
We register the address and port of the proxy server and save the changes
- Next, it is recommended to close and open the browser for the changes to take effect.
If the address and port are registered correctly and lead to a working proxy server, you will receive an anonymous Internet connection.
On Ubuntu
Linux and other systems in the Ubuntu family also have Proxy settings. In addition, it is possible to connect a whole list of proxies for automatic selection in case any server is not responding at the moment.
After restarting the browser, anonymity will be guaranteed if the assigned addresses are functional.
It is also possible to automatically configure Proxy. To do this, enter the commands in the terminal:
- $ gsettings set org.gnome.system.proxy mode 'auto' - enables auto-tuning;
- $ gsettings set org.gnome.system.proxy autoconfig-url http://my.proxy.com/autoproxy.pac - selects a server from the recommended list;
- $ gsettings set org.gnome.system.proxy mode 'none' - disables the proxy server.
Configuring Proxy in Browser
Some browsers allow you to configure a proxy server so that requests only from a surfing program are sent to an anonymous service. At the same time, other applications, messengers, will continue to work normally. You can also install an extension in the browser: a mini-utility that performs the functions of connecting to the Proxy.
Chromium-based browsers (Google Chrome, Opera, Yandex, etc.)
The Chromium engine does not have its own settings for connecting to a proxy, therefore system parameters are used, and browser menu items lead to the above-described browser properties.

Mozilla Firefox
Mozilla's browser software codes allow you to connect to the proxy server directly from your browser.
Safari
Similar to Chrome-based browsers, Safari does not have its own means of creating a proxy connection. Browser settings send us to Internet Explorera properties.
- Press the key combination Ctrl + P. In the window that opens, go to the "Advanced" tab (far right).
- Opposite the "Proxy" item, click the "Change settings" button. And then we register the address and port, as in the example above.

Proxy browser extensions
Modern browsers are a platform to which many additional utilities can be attached for the convenience of the web. Proxy widgets are no exception: there are tons of free and paid programs in the “store” of each browser.
Why proxy doesn't work and how to fix common mistakes
If a running server suddenly stops responding, there may be several reasons:
- proxy has stopped functioning;
- the provider has blocked access to this service;
- malware has appeared on the computer that changes network settings, including proxy.
The first thing to do is try a different proxy address. There are a lot of anonymous servers, the provider will not be able to block everything, just like all services will never be closed.
If several proxies of your choice refuse to work, or worse, you do not use an anonymous server to surf the network, but you get an error in the browser like "Connection to the proxy server is not available" - it means that this is the work of malware. Precisely programs, because antiviruses can often miss such a threat. To identify and treat this problem, specialized programs are needed. For example, Hitman Pro is a free scanning utility for finding, detecting, and fixing malicious software. Ideal for antivirus back-up and real-time system diagnostics.
Where to get the IP address and port of the Proxy server
Proxy databases can be found on the Internet. Many services even provide information about the health of the Proxy at a given time. Addresses are registered according to the following scheme: [port]. Examples of lists:
- https://2ip.ru/proxy/
- https://kupit-proxy.ru/spisok-proxy
Proxy is very easy to work with. Setting up the service does not take much time, and after that you will get full access to the information you are interested in anonymously and bypassing locks.
When opening sites in a browser, a user, especially after reinstalling or updating Windows, may encounter an error "Unable to connect to a proxy server", which is displayed on all pages on the network without exception. A similar problem can overtake when using any browser: Google Chrome, Opera, Mozilla Firefox, Yandex Browser and so on. The fact is that it is associated with incorrect settings of Windows itself or other problems, that is, it does not matter which browser connects to Internet resources through. As part of this article, we will look at what to do if the error "Unable to connect to the proxy server" occurs.
Why can't I connect to the proxy server
Most often, the error in question occurs due to a change in the settings of the Windows operating system of the connection settings from automatic mode to the option using a proxy server. This setting can be set by default in some assemblies of Windows (unofficial), and it can also be enabled after updating the operating system for one reason or another. It is also possible that a virus changes the settings on the computer, but it is quite rare.
What to do if you can't connect to the proxy server
If you cannot connect to the proxy server, you can fix the problem through Windows settings. This is done as follows:
After that, you need to restart your computer, and the error connecting to the proxy server should no longer bother you.
It should be noted that you can go to the settings of the local network parameters not only through the "Control Panel", but also from the browser. Using Google Chrome as an example, it looks like this:
Please note: If you use an extension in Google Chrome that configures proxy servers automatically, for example, FriGate, then you will not be able to change settings from the browser.
You can use similar methods to change the connection settings in any browser.
What to do if you cannot connect to the proxy server due to a virus
Above is the standard way to solve the problem when you cannot connect to the proxy server due to incorrect system settings. But there is a situation when virus applications deliberately change the connection parameters, while some of them do this after restarting the computer, and others directly while the PC is running.
If connection problems cannot be solved using the method described above, you need to check your computer for viruses. To check, you can use free antiviruses, for example: Zemana AntiMalware, HitmanPro, Microsoft Malicious Software Removal Tool, Spybot Search & Destroy, Avast and others. Before scanning your computer with antiviruses, it is recommended to check the list of recently installed applications and remove any unknown ones. Also, be sure to check the list of extensions in the browser that is used most often.
To avoid contamination of your computer with viruses, it is recommended to install applications only from the official websites of the developers or from other trusted sources. Be sure to pay attention to the terms of the user agreement during the installation process, which may include items related to the installation of "partner applications", which increases the risk of virus infection of the computer.
Users of a number of modern browsers (especially Google Chrome), when trying to go to any site, may encounter an error when opening this site and the corresponding message “ERR_CONNECTION_FAILED” At the same time, reloading the problem page usually gives nothing, encouraging the user to search the network various solutions to the problem. In this article I will tell you how what ERR_CONNECTION_FAILED is, what are the reasons for its appearance, and how to fix this and similar errors on your PC.
Understanding how to fix ERR_CONNECTION_FAILED
Translated from English, the text of this message ERR_CONNECTION_FAILED is translated as "Error, connection failed." And it usually means a situation when the user's computer could not establish a connection to the desired Internet resource for a number of the following reasons:
Fixing ERR_CONNECTION_FAILED
The ERR_CONNECTION_FAILED solution is as follows:
Documents and Settings / Username / Local Settings / Application Data / Google / Chrome.
What is the ERR_TUNNEL_CONNECTION_FAILED error
Close to the error I described above is the error « ERR_TUNNEL_CONNECTION_FAILED ". It usually occurs in a situation where your browser was unable to process the proxy response for a site.
To fix the error, follow the tips I described above for the error « ERR_CONNECTION_FAILED ". I also recommend running the command line as administrator, and there type the following commands, not forgetting to press enter after each of them:
ipconfig / flushdns
nbtstat –r
netsh int ip reset
netsh winsock reset
Alternatively, you can try reset your browser settings (in the case of Chrome, this is done by going to "Settings" - "Advanced" - "Reset").
How to fix ERR_PROXY_CONNECTION_FAILED
Usually, the "ERR_PROXY_CONNECTION_FAILED" error occurs when the user's browser was unable to connect to the proxy server. To solve this error, I recommend that you follow the whole complex of the above tips for both the first and the second of the above errors.
HKEY_CURRENT_USER \\ Software \\ Microsoft \\ Windows \\ CurrentVersion \\ Internet Settings
and delete the key " Proxy Enable key"(Move the cursor over this key, press the right mouse button, select" Delete "). Also here select the key " ProxyServer registry key"(If any) and delete it.
Alternatively, follow the above route (Chrome - "Settings" - "Advanced" - "Proxy server settings" - "Network settings") and uncheck the option "Use a proxy server for local connections). Click on "Ok" and restart your browser.
You can also use the advice given in the video below.
Conclusion
In this article, I have discussed the elimination of ERR_CONNECTION_FAILED as well as a couple of related errors. I recommend that you follow the entire complex of the above tips, they will get rid of the ERR_PROXY_CONNECTION_FAILED error (as well as those close to it) on your PC.
In contact with
Proxy connection error is a fairly common problem for users.
When such a problem occurs, messages appear on the screen:
- Failed to connect to Windows 10 / Microsoft Edge proxy.

- Log in to "Network and Internet".
- "Proxy" in the left menu.
- In the right pane, be sure to disable all options.
Several users reported that this solution works exclusively in Safe Mode, so be sure to enter Safe Mode.
Use the ipconfig command
The problem is related to your IP address. Just run a few commands:
Run Command Prompt as Administrator:
- Click Windows + X.
- Select "Command Prompt" ("Admin").
- If Command Prompt is not available, use PowerShell (Admin).
- Run the following commands:
ipconfig / release
ipconfig / renew
- Close the command prompt.
Many users reported that this solution is working.
Reset browser settings
Keep in mind that this process will disable all extensions and clear your cookies, so you will have to manually activate them. To reset Chrome, follow these steps:

Follow the steps:
- Press WIN + R
- Enter regedit
- When Registry Editor opens, in the left pane navigate to Computer \\ HKEY_CURRENT_USER \\ Software \\ Microsoft \\ Windows \\ CurrentVersion \\ Internet Settings.
- In the right pane, find the ProxyEnable and ProxyServer values \u200b\u200band delete them. To do this, simply select the value, right-click it and click Delete.
- When a confirmation dialog box appears, click Yes.
Be aware that modifying the registry is potentially dangerous, so be careful. If you run into any problems after making these changes, be sure to revert them and re-create the deleted values.
Today there are many users of modern computer systems based on Windows operating system who are familiar with the concept of a proxy server, or at least have heard of it. Let's see what it is and why there are situations when the proxy server does not respond.
What is a proxy server?
In simple terms, a proxy server is a specialized service that allows you to connect to the Internet or a local network through so-called indirect (indirect) requests.
In other words, the proxy server acts as a kind of intermediary between the user of the computer terminal and the requested resource. As already clear, it is not at all necessary that it be on the World Wide Web. But very often you can find the appearance of problems related to the fact that the proxy server does not respond. Now we will look at the most common situations and methods for eliminating them.
Causes of problems
As a rule, the proxy server does not respond mainly when using incorrect settings. It would seem that the addresses were entered correctly, but at one point the connection stops working. Why?
This is often due to incorrect or forced shutdown of Windows, for example, in case of a sudden power outage (in cases where there is no uninterruptible power supply), shutdown of some system services and applications when the "operating system" hangs, etc. In such moments, the proxy settings simply have the property of "flying". But you can fight this, and even very successfully.
In some cases, the problem that the proxy is not responding may be due to its own health. This can be temporary maintenance, software component updates, and more. And we are not talking about the fact that if the provider service does not provide services for connecting using a proxy, then it is absolutely pointless to configure its parameters.
The proxy server is not responding. What to do?
First, let's look at the basic proxy settings, which are called in the additional parameters of the properties of the default Internet browser. For standard Internet Explorer or Edge (Windows 10), these settings are configured through the standard Control Panel.
We will assume that the provider still uses a proxy. If the proxy server does not respond, Windows 7, for example, or any other modification simply does not recognize its actual address when trying to establish an intermediate connection.
What to do in this case? Yes, just enter the correct values \u200b\u200bof the addresses provided by the provider when the terminal is connected to the local network or the Internet.
Local networks should be mentioned separately. The fact is that failures, even those when the proxy server does not respond, Windows 8 can also interpret in its own way. This, incidentally, applies to almost all recent versions of Windows, starting with XP. Pay attention to whether the proxy setting is enabled for local addresses. If there is a check mark next to this item, it is strongly recommended to remove it. Quite often, the problem arises precisely because of this, since the system does not refer to the address of the proxy server itself, but to the identifier of another machine connected to the local network. Although such addresses, in theory, have nothing in common, nevertheless the Windows OS of all versions is not protected from such failures.
Using anonymous proxy servers
With anonymous resources on the Internet, which are proxy servers that allow you to change or hide the real external IP address of a user's computer while surfing the Web, the situation is somewhat different.
Here, basically, connection errors arise precisely because of the problems of the resources themselves. This often manifests itself in the fact that the browser displays a message that the gateway timeout has expired). It only means that the requested resource, which can work either as a proxy server or as a gateway, did not receive a response in time from the server located in the hierarchy of connections above it.
Here you can do the simplest way - just and in extreme cases (if you are sure that the resource is working) just restart the system. Perhaps, sometimes it may require disabling the antivirus or firewall or adding the site itself to the list of exceptions, because an antivirus or a firewall can block some sites, in their opinion, suspicious.
Conclusion
In principle, we have considered the most common situations and the simplest methods of correcting them, just without going into the technical side of the issue. Separately, it should be said that in most cases the lack of communication with proxy servers is not associated with any critical disruptions in the operation of operating systems. Rather, it is a special case.
It's not even about user settings, but about the performance of the resources of this type, especially in the case of using anonymizers. Actually, as can be seen from the above material, the problems can be solved quite simply. Sometimes you even just need to check if the network connection and access to the Internet are active, otherwise it also happens that the icon in the system tray shows that the connection is active, but in fact it is limited or absent altogether (most often in relation to connections based on Wi-Fi connections).
