Ubuntu – YouTube videos have a red tint

For a very brief time, Youtube recently exposed an experimental player on their site with fast and slow play capabilities, and this may be affecting the current player. If this is the case, it would help to clear your browser cookies.

Try the following

on your top panel

1. Go To connections.
2. Edit Connections
3. Pick "Wired connection 1 (or whatever name it has)" and click on edit.
4. Change MTU Value from Auto to 1492, and click on save.

I had the same problem before where it just showed me the animation with the little circles running and a few moments after, the message "there has been an error, try again later", if you have the same problem, then doing that should fix it, I was pointed in the right direction by a friend in this Question, just click on it and you'll see the comment.

Hope this solves your problem.
