Description

I get the following error "ERROR Error querying the server, waiting 5m".

I run the server on my QNAP NAS using Qnap Container Station and your minecraft server and backup docker images.

Here is the log from mc-backup :

```

```

And here is the log from the mc-server (I've just replaced the nas IP by SERVER_IP):

```

[12:36:31] [RCON Client /SERVER_IP #10/INFO]: Thread RCON Client /SERVER_IP shutting down

Thank you in advance, I'm very very new to all of this!
