How To Fix Proxy Server Isn T Responding

"The proxy server isn't responding", followed by a probable cause of the error and a couple of tips on dealing with it, is an error message that is displayed when a user affected by it attempts to access the internet through an internet browser such as Internet Explorer, Google Chrome or Mozilla Firefox.

In many cases, if an affected user has two or more browsers installed on their computer, they observe that one of their internet browsers works perfectly fine. The "Proxy server isn't responding" error message indicates that the proxy server that a person is using is not responding to the requests their computer is sending to it, and this is alarming for many users affected by this issue because most of them don't even use a proxy server to begin with!

In most cases, the "Proxy server isn't responding" error is simply caused by some kinks or issues with your registry and can be easily rectified.

Resetting Google Chrome usually doesn't proves fruitful so what i'd recommend is creating a new Chrome Profile. Before we do this; take a back up of your bookmarks so they can be imported later. See this guide for importing/exporting chrome bookmarks.

Exit Google Chrome completely.

Enter the keyboard shortcut Windows key +R to open run dialog.

In the Run Dialog window that appears enter the following in the address bar.

If after resetting the browsers, it does start to work then this is most likely caused by a adware which must be removed in order to stop it from coming back. To do this, you can use AdwCleaner (google it) to download it and install it, and then clean the adwares. However, If it still shows proxy server isn't responding error, then do a full scan using your antivirus software and remove any threats it finds, if it still won't work, then uninstall antivirus/malware and vpn, or other security softwares temporarily to test. If it then works, you can put your security program back, doing this will reset the rules configured in the firewall/antivirus, etc.
