With over an hour left in the Beta, I can’t login because of this error.
I’m also having the same issue after playing multiple hours everyday the beta has been out, I even logged in like 3 hours ago or so went to eat lunch came back and now I can’t log in due to this error.
The beta is over. The server must be offline.
I still have some friends playing so it can’t be over yet.
I have the same problem of error. So when I look better the app battle.net, there is a information that beta is over. Because of this I think thats is the cause. At night I will try in a different internet for test, but I still think that will ocour the same problem.
Ask to that friends if they are really in game.
