Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi there, I'm back on Nostalrius after like 3 months of not playing WoW, and I keep getting disconnected whenever I try to log in. I've tried in the morning yesterday and today, and in the evening and it just disconnects me every time...

Please help, and yes, I've seen some posts here about it.

I found the solution : you have to reset your password and it will be fine !
