The error im getting:

Im not sure what i did wrong, so can anyone help?

[timvisee]

You probably have to configure command to something that will start your Minecraft server.

# Command to start the server.
# Warning: if using a bash script read: https://git.io/JMIKH
command = "./run.sh"

I'd recommend to change it to the command which you use to start up your server when not using lazymc. Does that work?

[PhotonRBLX]

I got it to work by using "cmd.exe /C run.bat" but im trying to use ip portforwarding service software like playit.gg but it doesn't work when i try to forward 0.0.0.0:25565 to the ip provided by playit.gg, i used tcp, udp, tcp + udp and but me using the ip provided still isn't recognized by minecraft.

can you see if you can get it working yourself with playit.gg?

[timvisee]

can you see if you can get it working yourself with playit.gg?

I'm quite busy, and don't have the time to give this a shot myself. Sorry!

[kikoreta]

That's a problem with playitgg, when using the free "tier" it assigns you a public ip + port, so when you map your "localhost:25565" server to create a tunnel to playit it assign a random ip + port and that's what you need to use to connect to your server not the default 25565 port.

[skyelar7737]

instead of using "./run.sh" use something like (command = "java -Xmx12G -Xms1G @libraries/net/minecraftforge/forge/1.20.1-47.4.6/win_args.txt --nogui")
thats what i use and works for me, also i havent needed to use powershell so idk why your using that
