Incompatability with Lazytainer

[Player505]

I'm trying to set up a docker compose that both does backups and sleeps the minecraft container when no traffic is online. However, this doesn't appear to work. Bellow is my compose files and the console error that I get.

I'm assuming the issue is with the network mode on the minecraft container being service:lazytainer since the console error is about not being able to find the host. But when I add the same network mode to the backup container the issue persists.

version: '3.8'

  lazytainer:

Yes, I believe you're right. I'm thinking put backup service on the same network mode and set RCON_HOST to localhost.

Yes that worked. I got an authentication error since I forgot to set the RCON password on both the minecraft and backup container but once I did that it worked well. Here is my docker compose if you are interested.
