Hello getting following Error, can´t connect to the server getting an Network Error.

The Network Error isn't caused by the lithostitched metadata warnings. Your server is failing to start because port 25565 is already in use. The Main Error: **** FAILED TO BIND TO PORT! bind(..) failed: Address already in use. This means another server process is still running and using that port. If you haven't already killed the server process, check for running Minecraft/Java processes: bash ps aux | grep java
Look for a line that contains "minecraft" or "fabric-server" - you'll see a number in the second column, that's the Process ID (PID). Then kill that process: kill -9 [PID]
After the existing process is terminated, restart your server and it should start successfully.
The lithostitched errors are just metadata format warnings and won't prevent the server from starting. The alternate-current error at the end is a cascade from the failed startup, not the root cause.
