Server Connection Issues

[McFluryTV]

Describe the Bug

I have a server through BisectHosting, I was using BMC4 and the server was running great for a few hours, but now none of my friends can play on the server with BMC4, they'll join for like 10 seconds, there will be a lot of lag, and they'll just disconnect. The server runs great with BMC5, BMC3 Fabric, but there's connection issues with BMC4. I was running the server with 6GB RAM, but then the connection issues started occurring, so I upgraded to 12 and still nothing changed. I'm running the new 1.20.1 update that came out a couple days ago. This also is a brand new server, just made it today.

Reproduction Steps

1. Create a BisectHosting server hosting BMC4 1.20.1
2. Open Curse Forge and run BMC4 Forge
3. Go onto Server using the Bisect Server IP given
4. Own game runs great, but other people have unplayable connection issues and keep disconnecting
