Fix: Unable to connect to Proxy Server in Windows 10

If you don’t know what Proxy Server is then it is a redirect via an IP to the external site, usually used for anonymous surfing. If the IP / Proxy is down, or if it is configured incorrectly then you will get the error “Unable to connect to Proxy Server“. You do not need to turn the proxy settings on unless you intentionally set it up to browse anonymous if that is the case then you would need to check with your Proxy Provider otherwise your PC/SYSTEM can work without proxy. If it has been turned on for some reason then it is most likely due to a third party program you may have installed or by an anti-virus software that has tried to restrict access to other websites while it scanned your system for infections. So to fix this; proceed with the steps/methods below.

Check Internet Properties

Hold the Windows Key and Press R. Type inetcpl.cpl and Click OK. (it needs to run as administrator)  – You can also click Start and type iexplore.exe ; right click internet explorer and choose Run As Administrator.

Once done, reboot the PC and TEST. If it still won’t work, move to the Registry Editor Method below.

Change Proxy Settings via Registry Editor

It is important to back up your registry settings before changing it. Hold the Windows Key and Press R. Type regedit in the run dialog and click OK. To backup registry, after opening it, Click File-> Export, name the registry file, eg: backupreg and click Save. To import / restore from backup, open registry editor again, click  File -> Import, and select the file you exported earlier which is your back up. After it has been backed up; Navigate to the following path:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

In the right pane, locate the ProxyEnable string. Right Click on it and choose Delete. If there is a ProxyServer string, Migrate Proxy, and Proxy Override, right click on it and delete them as well.

  1. I’ve solved this by executing internet explorer in administrator mode
    Internet options > Advanced settings > Restore.
    Then, don’t close internet explorer, just close the session and sign in again.
    That would fix it for a while until it happens again, it’s frustrating me.
