[b]"Getting HTTP Error 407 - Proxy Authentication Required. How Do I Fix This?"[/b] or [b]"HTTP Error 407: Why Am

This might sound dumb, but have you tried restarting your machine?

Sometimes the proxy settings get stuck, and a reboot clears the http error 407.

If that fails, check if your browser has any extensions messing with proxies (looking at you, VPNs).

Also, if you’re on a work/school network, maybe ask IT for a proxy bypass list? Some sites don’t need auth.
