Issue

When I try to start my server i receive the following error :
FAILED TO BIND TO PORT!
The exception was: io.netty.channel.unix.Errors$NativeIoException: bind(…) failed: Address already in use

Reproduction Steps

  • try to connect
  • Try to update
  • Check that port 25565 is ok

Odd, have you tried stopping/starting the instance or rebooting your Linux machine?
