@TeamYouTube I was logged into my Youtube account earlier, I wake up from my nap and I'm suddenly logged out. I don't have any security emails or anything, just logged out. When I hit "log in", it just endlessly loops the "oops" screen.
I'm using the latest version of Firefox.
I got it sorted out about 10-20 minutes after tweeting, I kept trying to log in and clearing my cache and eventually gmail signed me out, and when I signed back in it and Youtube were both working again.
