It's not a solution but this information is helpful for identifying what is causing the problem.

The most likely cause is your router not being able to maintain the connection between MinimServer on the QNAP and your control point app for more than about 30 minutes. This is a known issue with some routers and it can sometimes be fixed by changing a configuration setting on the router. What router do you have?

Also, have you tried using any other media servers on your QNAP? If you have, it would be helpful to know whether the other server also times out after running for about 30 minutes.
