FsHostClient can’t find a session.

[Poppity]

Hello, i can't write on the fshost category, by the way i have a fshost server on dedicated machine in a datacenter i set up all server, can join in the webpage and login can see my server in fshostspy red icon but when i try to log in fshostclient can't find the session with an error pop up in fron of me...
I forwarded my ports in all machines. I can join in other servers but not in mine.
