Authentication in WebVeiw2 using `--proxy-server` argument

[dklassic]

Hello,

I am trying to setup Webview2 with proxy. Afaik the way to go is to use the --proxy-server argument.

I've tried HTTP and SOCKSv5 without authentication using --proxy-server="protocol://ipaddress:port", and it works as intended. However, when I tried setting proxy server with credentials using --proxy-server="protocol://username:password@ipaddress:port" both HTTP and SOCKSv5 leads to "ERR_NO_SUPPORTED_PROXIES" error.

So I had some questions regarding this:

• Does the --proxy-server argument currently support authentication?
• If so, how to properly set it up? And if not, is there a workaround?
