Serverpack
To run a modded server, you must use a server pack, not the regular modpack files.
What is a server pack?
Section titled “What is a server pack?”A server pack is a version of a modpack built specifically for servers. It includes the server-side mods and configuration but excludes client-only mods like mini-maps, resource packs, and shader packs. Client-only mods will cause your server to crash because they depend on graphical libraries that do not exist in a server environment.

What if there is no server pack?
Section titled “What if there is no server pack?”Some modpacks only distribute client files. If no server pack is available:
- Check if the modpack is available on Modrinth, which may offer a server pack.
- You can try to manually build a server using the client modpack files, but you must remove all client-only mods before the server will start. SquidServers support cannot help with this process, as we are not the developers of third-party modpacks.
If you see an error like the following, you are likely missing a server pack or have client-side mods installed on the server:
[main/ERROR] [ne.mi.fm.lo.RuntimeDistCleaner/DISTXFORM]: Attempted to load class net/minecraft/client/gui/MOD_NAME for invalid dist DEDICATED_SERVERMod and plugin troubleshooting
Section titled “Mod and plugin troubleshooting”Modpack, mod, and plugin issues must be troubleshooted by you, as we are not the developers of those modifications. Things you can try:
- Ensure mod/plugin versions match exactly between the server and your client.
- Check your logs to see if a mod is missing a required dependency library.
- Try using a wired ethernet connection instead of Wi-Fi.
- Read your logs for specific crash details, or contact the official mod/plugin developers directly.
Our support covers the SquidServers application itself, not custom third-party game modifications.
