Nostalrius Begins - Quality wow vanilla realm (1.12)

I think my account was banned and I have no idea why. I tried to logging kept saying connection error at first then I got a message saying to the wow website for being banned? Character name is Fellonie. I'm very confused seeing as I was on earlier today just fishing and did nothing. Then was just on 15 mins ago and had a power surge then try to get back on and this. Please help

It just signed me in now. Phew I was freaking out haha
