issue logging in....

Hello I play on 1 server most of the time, I am having an issue that even the admins of the server dont know what to do, every time I try and log into the server it says I cant connect because I am already connected to that server I have searched google and even this site I think but havent found this issue, I have restarted everything multiple times, even had the admin try and kick me from the server, and cleared out the appcache on steam, nothing has worked. I can log into other servers no problem any advice/ideas would be greatly appreciated

so no 1 has any ideas?

Get the admin to restart the server.
