Origins SMP server files
No. Origins SMP has no separate server pack on Modrinth, so the server is built from the .mrpack: the Forge or Fabric server for Minecraft 1.21.11, plus the pack's overrides folder and the server-side mods its modrinth.index.json lists. A modpack installer does this for you; our guide shows how to make a server for a modpack with no server pack.

Common Origins SMP crashes
What a Forge and Fabric 1.21.11 server running Origins SMP hits most. For any other error, paste the log into the free crash log analyzer.
- Wrong Java version. Origins SMP on Minecraft 1.21.11 needs Java 21. Started on Java 17, it stops with
UnsupportedClassVersionError: ... class file version 65.0, this version of the Java Runtime only recognizes class file versions up to 61.0. Java version fix. - Out of memory. Origins SMP (78 mods on the server) needs about 3–3.5 GB for 1–3 players;
java.lang.OutOfMemoryErrormeans it ran out. Out-of-memory fix. - Client-only mod on the server. The Origins SMP pack file marks none of its mods client-only, so this usually means one was copied over from a player's mods folder. Check a mods list with the client-or-server-side checker. Client-only mod fix.
- After adding or updating a mod. Mods you add to Origins SMP by hand usually crash it with a missing dependency or a mixin conflict.
- Ticking entity or block entity. The crash report names it and gives its coordinates. Ticking entity fix.
