Unable to connect to only one realm...

[:1]Hey folks,

Long-time player and I'm just now getting an error that won't let me onto USEast. It literally just says "Unable to connect to Battle.net," but I try to switch realms and I can sign in just fine onto West or even Europe. Anyone get this before? What is it and how can I resolve it? This is kinda bugging me, especially since I was just on USEast this morning.

Thanks,

-e.

edit: and...I'm a bloody idiot, there's a thread below explaining this. My bad. Except clearing the BNet preferences did nothing...
