Nostalrius Begins - Quality wow vanilla realm (1.12)

I have been playing here for almost a month and have had no problems logging in to the game. But since today I havent been able to play. I fill in my username and my password. It starts to connect . But everytime after about 2 seconds it disconnects with the words " Dissconected from server" .
Whats wrong ?

Same thing here. Connecting...Disconnected from the server.

Can't even get to the character screen.

Tried login and login2 , tried removing wdb and wtf folders, tried seeking other help on forums but nothing seem to work. Can someone confirm that the server is up btw ?
