If I had to guess, it’s a memory problem. I joined your game to see what I could find out, and it seems that the memory was around 1100 when I joined, and a couple of minutes later it was around 1200. Try looking through the scripts of the game and see what could be causing the memory leaks, such as not disconnected connections, or even loops that go on forever but don’t do anything. This post could help you to identify the memory leaks if needed.
