Ugh, proxy auth is the worst. If you’re on Windows, you might wanna try this:
Open *Control Panel > Internet Options > Connections > LAN settings*.
Tick the "Use a proxy server" box and hit *Advanced*.
Pop in your proxy details there.
If that doesn’t work, maybe your credentials expired? Happens a lot in corporate setups.
Btw, tools like Fiddler can help debug proxy issues, but it’s a bit overkill if you just need to fix http error 407.
