The server denied your connection attempt for the following reason: <Duplicate authentication>
I have restarted the computer and restarted the steam client. I cant log any of my characters onto Sklotopolis. I did try another WU server and got in just fine. Server restart needed? Or did I get banned?
I am having the same issue and when I verified the files, there was one that needed to be replaced. However, I still can't connect and get the same error of duplicate authentication. I can connect to other servers though.
