Just tried and it forwarded to YouTube for me.... Maybe try clearing all your caches?
Try in a private/incognito window to see if it still happens. If it doesn't you know it is cookies or caching.
The thing is if it is working for others, like it just did for me, there is no way to troubleshoot this as a problem on the forwarding side. The fact it work for me points to something with your setup or connection.
