One way to do that is to reset your entire network stack in Windows. In that case, you’ll have to fix that to eliminate the connection error in Chrome. Suppose your network settings have issues or are incorrectly configured. Your network configuration decides how your PC connects to the internet. But if you have to use a proxy server for some reason, then reach out to your server team to fix the issues causing Chrome to display an “err_tunnel_connection_failed” error message. Your sites should load when you disable the proxy. Launch Chrome and see if you can connect to your sites.
