When trying to open a website on Google Chrome, an error message can appear saying the browser was unable to establish a connection with the proxy server. This error pops up if internet connection settings on Windows 7 are incorrectly done, or if an installed program on the PC is infected. Like Google Chrome crashes or other browser-related issues, a proxy connection failed error is one that can be resolved.
After this, open the same website on and see if error still shows. If the page fails to load, go back to LAN Settings as mentioned above and see if the settings have reverted. If so, a computer virus or malware might be the issue.
Start the PC in Safe Mode and repeat the same steps to troubleshoot the Chrome browser issue. To access Windows in Safe Mode, follow the below steps:
If the LAN settings revert back to default despite changing them in Safe Mode, you have to remove the virus by running an antivirus tool. If you experience Chrome crashes or not opening a webpage, contact our browser support professionals via telephone for an opt response.
