Meanwhile, if you are not aware of activating any proxy profile on your computer, there are a few adjustments you need to make to get rid of the error. Disabling the proxy server works most of the time. However, it may not always work, and you need to explore further.
How to Fix err_proxy_connection_failed?
Before jumping to the fixes section, please confirm that you are facing the problem only on a specific browser or every browser you use. If the issue lies within a browser only, resetting the browser can help eliminate the error quickly. Meanwhile, restarting the router can also help sometimes. Otherwise, you can dig deep into the fixes, like changing the proxy server settings and resetting the network settings. Here, we have compiled a list of 6 fixes to help you eliminate the error without further hassles. Let’s get straight into them.
Check Browser Extensions
The first thing you need to do is check the browser extensions. If you have installed an extension that is probably malicious, it can interfere with the proxy settings of your browser. Therefore, it would be helpful to disable the extension and check if the issue persists. The steps to disable and remove extensions are similar in most browsers. Here, we are referencing Chrome browser for elucidation purposes.
Disable VPN
If you have activated a VPN on your PC, it can also be the reason behind the error. You probably have not set up the VPN profile correctly or are using a free VPN service that is causing the error. You can check by turning off any third-party VPN applications or deleting VPN profiles from Windows.
Change Proxy Server Settings
Next, you need to check if the proxy server is activated in your computer’s network settings. When the proxy service is activated, the computer tries to connect to the Internet via a proxy server, which can result in an error. Here’s how to disable the proxy server:
Disable Proxy from Registry Editor
A few keys in the Registry Editor, like ProxyEnable, ProxyServer, and MigrateProxy, are concerned with configuring proxy on your computer. Therefore, deleting these keys will disable the proxy functionality and help you eliminate the error. But before you start making changes, please create a backup of your registry.
Renew IP Address and Reset TCP/IP Stack
Some websites do not allow proxy users to access their websites. So, chances are that your IP may have been blocked or flagged, and you are facing the proxy error. In such cases, it can be a good idea to release the current IP and get a new IP from the router. When you renew the IP, you are assigned a new address from the router using the DHCP network management protocol.
Reset Network Settings
You can reset network settings as a last resort to fix the error. Resetting the network will reset all the customized network settings and revert them to factory defaults. You should not face a problem after resetting the network settings. Else, you need to contact ISP to figure out the problem.
