Problem Description


I have been trying to play a modpack on my server for a few hours now but I cannot quite get it to work. Im running the server using Forge v43.3.5, I have the Better MC 1.19.2 v20 (also 43.3.5) but in-game, an error message comes up saying that “Incompatible FML modded server mod list is not compatible”

Reproduction Steps

  • Uploaded the Modpack to a mods folder
  • extracted the .zip file
  • Checked that the versions match (forge 43.3.5)

Make sure all mod jar files are in your local mod folder, i had a problem a while back that some of them were randomly disappearing.

The “Incompatible FML modded server mod list is not compatible” message in the server list means nothing, you should still be able to join if you’ve set things up properly.
