My game servers consistently shutdown every 20-30 minutes for the same reason (Error 275)

Basically, my game (ORFA | New Test Pitch - Roblox) shuts down for the same reason of 'Roblox has shut down this server for maintenance. Please try again. (Error 275).

I have no idea why but I’m confident it’s not a virus. I’ve tried many different solutions including rewriting scripts, deleting unneeded scripts etc etc.
I believe it’s a memory leak however the memory never rises that much during the play session and everyone’s ping consistently stays low. It’s like one second you’re playing fine with no issues and the next you’ve disconnected. It’s very weird.

If anyone could help me find the issue then that would be greatly appreciated.
Thanks!
