Problem Description
Issue
Hey, there! I am currently attempting to port over our existing Minecraft Java server that uses Fabric to launch. I’ve downloaded all files except the world files from the old server and uploaded them to the new server so that I can complete the initial setup before porting the world files. I’ve replaced the existing minecraft_server.jar file with the jar file used to launch our current server (obviously renaming it to match the new jar file). However, when I restart the server, I receive a message saying that there was an error and to check the logs, but no logs are generated afaict.
Any help would be appreciated with this, thanks!
Reproduction Steps
- Copy existing Fabric server to Hosting host
- Replace existing minecraft_server.jar file with Fabric server’s jar file
- Launch and recieve error but no log (afaict)
