Some Chrome browser issues are common on Windows PC. If you have encountered the Unable to Connect to the Proxy Server error on Google Chrome, follow the below steps to troubleshoot the issue. Power users can make the most of Chrome but only if the problem has been resolved to full browsing satisfaction.
The error message indicates exactly what it says – Chrome fails to connect to a website you are trying to open. So first, close all open tabs on the browser including the tab showing the error message. Then follow the below steps to troubleshoot the Chrome browser issues.
Open the same website once you apply all these changes to Settings on Google Chrome. Check whether you are getting the same proxy server error on the browser. If so, follow the same troubleshoots once again and check to see if Google Chrome Settings are reverted to how they were prior to changing. If the Settings have reverted automatically on Chrome, then it is likely a software program installed on Windows PC may be causing the reversion.
If that is the case, restart your computer in Safe Mode to retry the same troubleshoots as mentioned above. For that, remove any CD, DVD, Floppy Disk, or USB from the PC, and do a system Restart. When PC reboots, hold the F8 key prior to Windows logo screen. In case you have more than one version of Windows installed, highlight the Windows version having the problem when it boots up using the arrow keys and then press F8. On the Advanced Boot Options, highlight Safe Mode and press Enter.
