Error Querying the server #88

Open AndrewTevebaugh opened 2 years ago

AndrewTevebaugh commented 2 years ago

Hello, I just tried to get this container back up and running after not running it for a few months and I noticed that the backup worked successfully the first time around, but after that it would not connect to the minecraft server container.

As you can see it generates the first backup successfully on startup, but after that it cannot seem to connect to the server.

Can you set DEBUG to "true" and then provide that output?

I'm not really sure what part of this is important so I apologize for the length.

Thanks, yes, expected a lot of output. FYI here's the bit I was looking for

mc-monitor status --host localhost --port 25565 --show-player-count
+ PLAYERS_ONLINE='failed to ping localhost:25565 : could not connect to Minecraft server: dial tcp 127.0.0.1:25565: connect: connection refused'

Can you double check the Minecraft server itself isn't outputting errors or anything around the time of that?

AndrewTevebaugh commented 2 years ago

No errors from the server itself, however I did notice that the blurb you pointed out is trying to access port 25565. This is the backup for my 2nd minecraft server I am running. My first server uses the port 25565 and my second server uses port 25566. I tried to set the RCON port for the second server to 25576 instead of the default 25575 (from what I understand). However I just checked and the port of the docker container for the second server is 25565/tcp, 25575/tcp, 0.0.0.0:25566->25566/tcp, :::25566->25566/tcp For the first server it is this: 0.0.0.0:24454->24454/udp, :::24454->24454/udp, 0.0.0.0:25565->25565/tcp, :::25565->25565/tcp, 25575/tcp Note: the extra port on the first server is for a voice chat plugin

itzg commented 2 years ago

Can you provide the container configs for that backup container and it's corresponding server? Going over loopback, the container port mappings won't be utilized, so was wanting to cross check the internal ports configured.

This is the contents of my docker-compose file:

Ah, you're missing SERVER_PORT on the backup service.

Better yet, I really recommend you don't change the SERVER_PORT and RCON_PORT values since the port mappings can adjust for host side port conflicts.

AndrewTevebaugh commented 2 years ago

so what would that look like? Would I just remove all of the SERVER_PORT and RCON_PORT from both containers and change the port mapping to 25566:25565?

EDIT: I tried that and it didn't work.

itzg commented 2 years ago

Can you clarify in what way it didn't work?

Instead, you can go back to your previous but add the missing SERVER_PORT to your backup service.

AndrewTevebaugh commented 2 years ago

I tried doing what you recommended by removing the SERVER_PORT and RCON_PORT values and adjust the port mappings. Like So:

services:
  ProjectOzone:
    hostname: ProjectOzone
    image: itzg/minecraft-server:${IMAGE_TAG:-java8}
    ports:
      - 25566:25565
    environment:
      MEMORY: 6G
      EULA: "TRUE"
      TYPE: FORGE
      VERSION: 1.12.2
      MOTD: Project Ozone
      ENABLE_RCON: "true"
      RCON_PASSWORD: "password"
      TZ: "America/New_York"
    tty: true
    stdin_open: true
    restart: unless-stopped
    volumes:
      - ./ProjectOzone:/data
  ProjectOzoneBackups:
    image: itzg/mc-backup
    environment:
      RCON_PASSWORD: "password"
      BACKUP_INTERVAL: "4h"
      TZ: "America/New_York"
      PAUSE_IF_NO_PLAYERS: true
      BACKUP_METHOD: restic
      RESTIC_PASSWORD: password
      RESTIC_REPOSITORY: /backups
      PRUNE_RESTIC_RETENTION: "--keep-hourly 1 --keep-daily 7 --keep-weekly 5 --keep-monthly 12 --keep-yearly 75"
      DEBUG: TRUE
    volumes:
      - ./ProjectOzone:/data:ro
      - ./ProjectOzone-Backups:/backups
    network_mode: "service:ProjectOzone"
    restart: unless-stopped

I was able to get everything functioning by adding SERVER_PORT to the backup service, however I would like to understand why the other attempt to fix the issue did not work.

itzg commented 2 years ago

I just realized why the first suggestion didn't work. By default it won't update the server.properties file. Adding OVERRIDE_SERVER_PROPERTIES: "true" will get it working I think.

Thank you itzg! This solved a similar issue for me.
