Problem Description

Issue

It gives me an error saying the files are wrong, but everything runs perfectly from my Minecraft client, and this should basically work the same. I don’t know if I messed something up, but it should be simple: first install the Forge version, put the mods in the mods folder, and that’s it (that’s how I did it in my Minecraft and it works without any issues). This should work the same, but it throws an error.

Reproduction Steps

  • I created the server.
  • I changed it to Forge with its corresponding version (47.4.5).
  • I noticed that in the files there was a “download from Forge,” but in the versions section it showed 1.21. That didn’t make sense, so from my versions folder I took out 1.20.1-forge.
  • I added the mods.
