Can't join server, Error WOW519009328


After logging in, there is list of servers. I’m able to click any of them.
But after 2 minutes, I get the message:
You have been disconnected. (WOW51900328)

I did repair from the launcher plus an reinstall without luck.

Could I get some more information about this error, and when will it be resolved?
