xxMueller

I found the cause, I removed the certain mod that was causing it.

This just started showing up randomly after I installed a mod, i removed the mod and it still crashes with java.lang.reflect.InvocationTargetException.

I did until I fixed it by restarting server

I have 22 mods, the multiplayer screen says 0/40 but the server settings on their page says 19/40 1.15.2 forge newest

My server says 13/40 online while having no one actually playing. The server owners said it was a problem with forge and how it detected online players.
