Fresh Up Server Crashing Mid Game

After much trial and error, I've got a server up so my brother and I can play together. The only problem that keeps persisting no matter what I do is the server crashing. We can always make it through a hole or two before it crashes, with the occasional third hole. It mostly happens during the score sheet screen during hold transitions. Is there any way to remedy this, or are my server files just bad? I got both the client and server files from here: https://drive.google.com/drive/folde...lI4NzhMQnhaMm8

Any help would be greatly appreciated!
