Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I have been repeatedly logging in over the past hour to only be repeatedly disconnected. At times I'll make it into a battleground and then be disconnected in three minutes. Other times I won't make it past the character selection screen. I have never had this issue before, I have also reset my internet (which is working fine for anything else including another WoW server that I have been logged into for the last five minutes without issue). Given that I have been able to use another server successfully without interruption, this may be an issue on your end.

Did u download and use a new addon recently,?
maybe your newest addon causes this
