Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello , after the last server's disconnect , i am unable to login. I get the message "Disconnected from server". I read every topic about login problems , tried everything like deleting WTF and WDB folders , disabled all my addons etc. All my friends are online playing and i am the only one with this problem. An in real life friend of mine tried to log in with my account to check and he gets the same message. Can someone help me? My account name is "Zisakos" and char name is "Snobya" (Undead rogue)
Thanks a lot..

I checked the log in screen too , to see if it tries to connect to Nostalrius or another server and its on the right server.A friend of mine opened a ticket to a gm and he asnwered that i have to make a post on the forum. My problem still reimains. 8 Hours later and i still cannot login. Any help?
