I'm having the problem to. I was about to start The Newsroom and then I can't log. It's saying I don't have HBO subscription. I pay for it, so I do have HBO and was watching it last night fine.
Any status on the supposed outage?
It's not working for me right now either. It's pretty unreliable, but sometimes it works. Seems like it gets fixed whenever somebody complains to the right person, e.g. things would get fixed right before a Game of Thrones episode.
