Server: Minecraft
Issue: Anything outside of "latest" server version, the Docker cannot find the Forge .jar. Using an older version of Forge which requires jre11 (which already has been setup in edit and confirmed working). Tried shortening the names of the .jar files as well, so see if that helped. Nothing I can see out of place.
(trying to run a server with Zombie survival Mod. Only thing I can find is Forge, but I'm aware that it can be picky within Docker.. so if you recommend anything outside Forge that'll support mods, I'm all ears to suggestions)
