Unable to connect to the proxy server

ERR_PROXY_CONNECTION_FAILED
Hide details
A proxy server is a server that acts as an intermediary between your computer and other servers. Right now, your system is configured to use a proxy, but QtWebEngineProcess can't connect to it.
If you use a proxy server...
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Chromium menu > Settings > Show advanced settings... > Change proxy settings... and make sure your configuration is set to "no proxy" or "direct."
