Nostalrius Begins - Quality wow vanilla realm (1.12)

I got locked out of my account for incorrect login credentials. How long do I have to wait for it to be lifted? I've already been waiting 30+ minutes and tried to login and it gave me the same response.

In case this isn't resolved:

It should be 10-15 minutes you're locked out of your account. Can you confirm that you aren't banned though?
Login to https://en.nostalrius.org/ and it should tell you if you are banned.
