Why i get disconected every 1/2 hour?

Well its not that the exact time i can be online sometimes is longer o short.
I get a message that says "you are disconnected from game server" and the options reconect and ok.
When i click on reconect i get to the log in screen but with no response, its like freeze but after a while it says a message that disapear really fast it says something like "Cannot conect to serve unauthorized...." and the game closes.
Then i start the game again and get the error "you are already logged in" then i try again and it looks like it works but it crash again and it show the message "Failed to connect to game server" and it closes.
I start the game once again and get the error "You are already logged in" then i try again and it finally works.
I have to go all over this proces every short amount of time. Please help i dont know what to do.

Note: i Dont have this issue in the original server.
