Server Crash: NoClassDefFoundError: org/lwjgl/Version (Sodium on Server)

What it looks like in the log

java.lang.NoClassDefFoundError: org/lwjgl/Version

How to fix it

  1. Stop your Minecraft server if the process is still running.
  2. Open your server's 'mods' folder and delete the Sodium .jar file (e.g., sodium-neoforge-*.jar).
  3. Check your server's 'mods' folder for any other client-only addons that depend on Sodium (such as Iris, Sodium Extra, or Reese's Sodium Options) and remove them from the server as well.
  4. Start the server again; players can still keep Sodium installed in their own client 'mods' folder when joining.
