Description

Since today i'm receiving an "urlopen error Tunnel connection failed: 403 Forbidden" while using youtube-dl with proxy for any YouTube-files. I'm using Luminati.io as a proxy service and it was working like a charm until today. I've already switched to new proxy-ips, with no success.

Maybe the proxy-routine with YouTube has changed? Or maybe YouTube might have disabled all proxy access through Luminati at all?

Obviously proxy issue, nothing to do with youtube-dl.
