Nostalrius Begins - Quality wow vanilla realm (1.12)

I recently dc'd from the main server and thought there might have been something wrong with it when the game prompted me to select a server from the list on relog. Trying to connect back to the Nostalrius server wasn't working, so I tried to logon to Test Realm isvv2. However, doing that instantly gives me a "Disconnected from Server" message without any way to get back to the main server. Can someone help me here?

If it's not fixed yet, you can delete your WTF folder and the list will return when you log back in. But this also messes with addons.

On the realmlist file you can change it to:
SET realmList "login.nostalrius.org"
SET realmName "Nostalrius Begins"

Then it won't pull up the others outside the main one.
