Error: Unable to connect to the proxy server

Comments: 0

For each user, the main thing is the stable operation of the ego of a personal computer. How unpleasant it can be when, by launching a web browser instead of the desired page, you receive an unexpected message with the error "Unable to connect to the proxy server". It occurs on different operating systems, popular for most Chrome, Opera, Firefox and creates inconvenience in work, and sometimes a stupor from not understanding what to do. Why this is happening and how to deal with it, we will figure it out further.

"Unable to connect to the proxy server" reasons

It is worth remembering that a proxy server is, first of all, a certain set of settings that configure the operating system so as to gain access to the network different from the standard one (for example, a corporate network with restrictions), and therefore can affect the operation of other software.

If you receive such a message while opening your web browser, you should understand that something went wrong with the proxy server settings; among the possible reasons, you should consider other common options:

  • Parallel use of software that conflicts with proxy settings (for example, shared port)
  • Installing incompatible applications, extensions, and their automatic updates often cause settings to fail
  • Using VPN servers
  • Damage to the system by viruses and malware that makes changes to the network access settings, trying to redirect you to the right place for the virus
  • Blocking by antivirus or firewall
  • Using a low-quality proxy server

Although it is believed that the problem occurs more often on browsers that use a common platform, the error does not always look the same. You can get it in the following forms.

Unable to connect to the proxy server on Chrome


Unable to connect to the proxy server on Opera


Unable to connect to the proxy server on Firefox


How to eliminate the error

In most cases, a simple procedure known as "Reset Proxy Properties" can help resolve the problem and can be done by anyone. But if you are in a large corporate network, with delimited access levels, then it is better to contact the system administrator with this matter.

Depending on the operating system, you can execute it in the following ways.

Windows 10

In the tenth version, we need to get to the "Proxy server" settings

  1. Press the Win key or click the mouse on the “Start” menu. In the growing menu, as some "IT gurus" like to say, we go to "Settings".

  3. The next destination point among the Windows settings is "Network and Internet", where they are already waiting for us to select the "Proxy" setting, this is where we will reset.

  5. On the right side of the window there are automatic and manual proxy settings. It is important for us to deactivate all the switches, including "Automatically detect settings", "Use setup script", "Use a proxy server". That is, transfer to an inactive state or, in a simple way, turn it off.

Next, restart our web browser and check the result.

Windows 7

In the seventh, everything is the same, here you first need to write the query "Internet Options" in the search bar in order to be able to reset the proxy server settings.

  1. Select "Internet Options", in the window that opens, look for the "Connection" tab.

  3. In the part of the window describing the settings of the network parameters, click on the "LAN Settings" button, which is located at the bottom.


  4. Remove all active checkboxes and click the "OK" button to save the changes


The next step, as in Win 10, is to check the result of the reset.
