"You are not logged in." for chat at all times

For whatever reason, I can never get in to the live stream chat. I always get the message "You are not logged in.", and it doesn't give me any way to sign in. On the GB main page I show as signed in correctly. Example, right now I'm watching the Breaking Brad stream, but am not able to get signed in to chat.

When in doubt, log out.

And then log back in. And then chat! Worked for me.

Hah, wow that actually worked. Now I feel dumb. It's been happening both at work and at home for a few weeks. Thanks!
