Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I have like 3 accounts on Nostalrius. I havent played for awhile, and I cannot seem to log into one of my accounts. I can log onto my other two just fine, but when I try to log in to this one certain one, it immediately just says "disconnected from server" right after "authenticating." How can I fix this?

Character name on the account, I think (its been awhile) is Chumps on PVP server.

Thank you.

Have you checked if you disabled the home country IP-lock in your account settings?
Go to your account settings, change your password and disable IP lock. This option seems to be causing some trouble for some players.

it worked thanks man
