Server Help Constantly Disconnected From Own Server

Hello all!
I created a dedicated server on my computer that I open whenever my friends or I want to play Starbound. It works really well, however I constantly get disconnected every 30-40 minutes with the message "Client server connection no longer valid!" Before I get disconnected, the world stops loading and everything stops moving. I could join back immediately. This gets annoying cause sometimes I go moving for solarium, volium, etc. and I go and put everything in my storage, but I get disconnected and when I join back, all the items are gone. Also, joining back is a huge hassle as well, because getting disconnected 8 or more times a session gets annoying. Please help!
