This error happens when the mod is not correctly installed on the server.

Try the following:

• Ensure that you have placed the mod jar inside the mods folder of the server.
• Ensure that you are running the correct mod loader (NeoForge, Fabric or Forge) on the server.
• Ensure that the Minecraft version and mod loader of your mod jar match what you are running on the server.
• Bukkit, Paper, Spigot and other servers from the plugin ecosystem are not supported. Mods require the server to be running through their associated mod loader.

If you are using a server hosting provider, consult their documentation on how to add mods to the server.
