[PC] Connection Closed problem.

Dear Top Eleven managers, I often encounters the error "Connection closed, try to reload application."
I tried Google Chrome, Firefox, Opera and even Internet Explorer while the same problem persists. The error will pop-up once I leave the game idle for no more than half an hour. Even though reloading the application is not a big deal for me, but I'm here to ask for solutions to solve such problem. I would be really appreciated for anyone who can solve this error. Many thanks!
