My Minecraft nitrado server doesn't work what?

I don't quite understand why this doesn't work here:
Try to connect to container…
Connection to the container established.
[92m Starting game server now… [0m
Wed, Apr 15, 2020 4:40:33 pm +0200: Starting game server
Script started, file is / dev / null
/runscript.sh: line 1: cd: / mnt / MCMA: No such file or directory
Script done, file is / dev / null
[92mGame server exited successfully… [0m
Connection to the container lost.

I have doubts about the safe operation of a server…

runscript.sh: line 1: cd: / mnt / MCMA: No such file or directory

there should be the mistake

How do you fix it?

Secure your map and reinstall the server.

Don't go to Nitrado Support, they are always very helpful.

I don't know your server, so I can't help with that. Save map and all important data and then reinstall

Just wanted to play a modpack with a friend, so a 4 slot server
