Can't Logging in into the game

yesterday i was doing just fine to play on Frostwolf realm, but today i can't login and this is the first time i can't login into the game and I have never encountered this problem before)

i saw 2531 players online on the website and when i refresh the number is changing, but why i can't logging in into the game?

when i type my id and password it says success! but it stay for quite long and then appear realm box that contain realm name, type, characters, population and Frostwolf realm is highlighted by green color so that's mean the realm is online (red highlight for realm offline) and when i press "okay" a dialog box Logging in to game server there's nothing happend just dissapear.

ps: also when i try to connect to Cata realm and the problem is same

I got the same problem as you with Icecrown realm. I got crashed and have to relog but then this happened. It always connect normally then stoped at the success! and after awhile it will switch to the realm panel.

Im with the same problem on Lordaeron

Yes.. I'am with the same Problem on Lordaeron.

And I can loggin any other server

i thought i was the only who have this problem :(

i don't know whats happened but now i can login into the game, i'm just waiting for the reply on the forum while i'm playing other games. but the question is what cause this problem? can staff explain this?

Yeah I just tried to log into Frostwolf and the realmlist is gray so I cannot login. Anyone from the staff with a solution?
