Servers

Also make sure you only ever download Forge from https://files.minecraftforge.net

Have you tried repairing the instance?

Network channels must be registered during FMLCommonSetupEvent. Not at some random time during some random static initializer.

I removed OresAboveDiamonds and I also removed AdditionalEvents because it said something about loot tables and I thought that might fix my problem (No longer does the console output Loot Table errors). I had to remove two other mods that used AdditionalEvents (LavaBaubles and UnstableTools) and after that, the server was starting up but I ran into another issue I forgot to mention. Sometimes when generating a new world it will freeze at 97% or somewhere near that which makes me think it might be some sort of generated ore or structure that is causing the crash. It happens sometimes but not every time. I provided the debug logs, hopefully you can figure it out because I can't lol.

Post your full logs, and if you're fine with it the world save.
