Nostalrius Begins - Quality wow vanilla realm (1.12)

Greetings, just tried second realm in realmlist ans instantly got DCed.
Then tried to reconnect, but it's sending me to that realm and got DCed again.
So i tried to delete WTF folder and try again.
It didn't worked, auto 'Disconnected form the game'.
What should i do to fix that?

I tried to edit my realmlist to:
realmlist login.nostalrius.org
Realmname "Nostalrius Begins"

Didn't work too.

I can't connect either, havent been able to the entire day

I can't also. Been 10 hrs unable to connect. It keeps me in the realm selection screen constantly.

Same, though fore me it just says "Connecting" then "Disconnected from server" after I type in my login information. Are there people in-game right now? I really want to play damn it >.<

OK i fixed my problem. The thing is that realmlist must be in .wtf format.

Yeah mine is already realmlist.wtf but i just cant seem to connect idk why.

Same problem, getting instant dc tried with realm1 and 2.
Was completely fine befor i go dinner

Anyone figure out what's the problem?
