Description

When trying to download a geo-restricted video from YouTube using the --proxy parameter youtube-dl crashes with one of the messages seen in the two logs above. It is not relevant what geo-restricted video I try and it is not relevant what proxy I try. Proxy works in browser but I always get either the first or the second message in youtube-dl.

Most likely proxies are broken/misbehave/non-socks5.

Proxies work properly in other applications.
