Having trouble connecting to the rcon
Hello,
I have a minecraft server running in a docker container and I can't connect to it via this tool.
I've checked the other issues and tried what I could, but no success.
My docker-compose for the server is:
version: "3.8"
services:
minecraft-server:
image: "itzg/minecraft-server:multiarch-latest"
container_name: "mc-pi"
ports:
- "25565:25565"
- "4711:4711"
volumes:
- "~/mc/data:/data"
networks:
- Minecraft
environment:
EULA: "true"
ENABLE_RCON: "true"
RCON_PASSWORD: "sabin"
RCON_PORT: 25575
TYPE: "PURPUR"
VERSION: "1.16.5"
PURPUR_BUILD: "LATEST"
MEMORY: "1000m"
tty: true
stdin_open: true
restart: always
volumes:
mc:
networks:
Minecraft:
And the docker-compose for the rcon is:
version: "3.8"
services:
web:
image: itzg/rcon
environment:
RWA_USERNAME: admin
RWA_PASSWORD: sabin
RWA_ADMIN: "TRUE"
RWA_RCON_HOST: minecraft-server
RWA_RCON_PASSWORD: sabin
ports:
- 4326:4326
- 4327:4327
networks:
- other
networks:
other:
external: true
name: mc_default
The folder structure is as follows:
.
├── mc
│ ├── data
│ ├── docker-compose.yml
└── rcon
└── docker-compose.yml
Also the docker network:
docker network ls

I've also tried using only one docker-compose file, same results:

Any help is much appreciated! Thanks in advance!
Do the rcon web container logs show anything? Try adding the env var OVERRIDE_SERVER_PROPERTIES: "true" to your minecraft-server service since it may not be updating the server properties with your desired rcon password.
Same problem here.
with this docker-compose.yml file:
version: '3.3'
services:
web:
image: itzg/rcon
container_name: web
environment:
RWA_USERNAME: admin
RWA_PASSWORD: admin
RWA_ADMIN: "TRUE"
RWA_RCON_HOST: 127.0.0.1
# is referring to the hostname of 'mc' compose service below
# needs to match the password configured for the container, which is 'minecraft' by default
RWA_RCON_PASSWORD: minecraft
RWA_RCON_PORT: 32648
ports:
- 4326:4326
- 4327:4327
mc:
container_name: mc
image: itzg/minecraft-server
ports:
- 25565:25565
- 32648:25575
environment:
OVERRIDE_SERVER_PROPERTIES: "TRUE"
EULA: "TRUE"
ENABLE_RCON: "TRUE"
RCON_PORT: 25575
Doesn't work either with RWA_RCON_HOST set to mc
I have the same issue. I just completely deleted my old MC volume and all old images and re-setup everything with your sample compose file: `version: '3.3'
services: web: image: itzg/rcon environment: RWA_USERNAME: admin RWA_PASSWORD: minecraft RWA_ADMIN: "TRUE" # is referring to the hostname of 'mc' compose service below RWA_RCON_HOST: mc # needs to match the password configured for the container, which is 'minecraft' by default RWA_RCON_PASSWORD: minecraft ports: - 4326:4326 - 4327:4327 mc: image: itzg/minecraft-server ports: - 25565:25565 environment: EULA: "TRUE" TZ: America/Chicago restart: always`
Log after start-up:
[18:37:16] [Worker-Main-8/INFO]: Preparing spawn area: 97% [18:37:20] [Server thread/INFO]: Time elapsed: 265595 ms [18:37:20] [Server thread/INFO]: Done (339.510s)! For help, type "help" [18:37:20] [Server thread/INFO]: Starting remote control listener [18:37:20] [Server thread/INFO]: Thread RCON Listener started [18:37:20] [Server thread/INFO]: RCON running on 0.0.0.0:25575 [18:37:29] [RCON Listener #1/INFO]: Thread RCON Client /172.19.0.3 started
Only I changed was the TZ setting and the restart flag. What am I missing here?`
BTW I also tried to change the server in the RCON Web admin to the local IP which was 172.190.2 as well as the docker server name:
b42a062394f0 itzg/minecraft-server "/start" 16 hours ago Up 16 hours (healthy) 0.0.0.0:25565->25565/tcp, :::25565->25565/tcp, 25575/tcp mincecraft_mc_1
And there is nothing in the log files on the RCON container:
root@neutral:~# docker exec -it 2c64df3217db /bin/bash root@2c64df3217db:/opt/rcon-web-admin-0.14.1# ls CHANGELOG.md LICENSE README.md config.template.js db logs node_modules package-lock.json package.json public src startscripts root@2c64df3217db:/opt/rcon-web-admin-0.14.1# cd logs/ root@2c64df3217db:/opt/rcon-web-admin-0.14.1/logs# ls root@2c64df3217db:/opt/rcon-web-admin-0.14.1/logs# ls -lha total 12K drwxr-xr-x 1 root root 4.0K Jun 9 2020 . drwxrwxr-x 1 root root 4.0K Apr 17 2021 .. -rwxr-xr-x 1 root root 14 Jun 9 2020 .gitignore root@2c64df3217db:/opt/rcon-web-admin-0.14.1/logs#
Using the example still works fine for me:
https://github.com/itzg/docker-rcon-web-admin/blob/master/docker-compose.yml
Start from there and make one change at a time until you find where the config is wrong.
Like I said that was the compose example I used. I only added the restart always and the TimeZone option. But I will retry again without those set.
Same thing, blank slate using default compose config. No error in the rcon running container or with RCON on the minecraft container. What does you local docker network look like? Here is mine:

That's all I can think of.

Same issue here. Using provided docker compose file with 0 modifications. I get the same image as OP.
I'm seeing the following in the rcon admin container logs:
2023-05-22T13:34:29.034Z Invalid rcon password for server minecraft:25575
{"host":null,"websocketUrlSsl":null,"websocketUrl":null,"port":4326}\00\00\00\00\00\00J2023-05-22T13:36:51.115Z Invalid rcon password for server minecraft:25575
Could this be part of the issue? I am using the example compose file here: https://github.com/itzg/docker-rcon-web-admin/blob/master/docker-compose.yml. I haven't changed anything from that.
One thing of note: When I run through portainer, the container names are modified to be this:
minecraft-web-1 minecraft-mc-1
The name of the Portainer stack I created was called "minecraft."
Sorry, I had forgotten to update the example due to the default, randomized RCON password feature. Please use the latest:
https://github.com/itzg/docker-rcon-web-admin/blob/master/docker-compose.yml
Hi, I'm still having this issue, i set the password in my docker-compose.yml but it still changes everytime. So i cannot connect to rcon :
minecraft-kingdom-survie: image: itzg/minecraft-server ports: - 25570:25565 - 25575:25575 environment: EULA: "TRUE" MODE: "creative" MEMORY: "4G" ONLINE_MODE: "FALSE" # password needs to be explicitly set, # otherwise random one is generated at each startup RCON_PASSWORD: "demo" tty: true stdin_open: true restart: unless-stopped volumes: # attach a directory relative to the directory containing this compose file - /home/Config/MinecraftJavaKingdomSurvie:/data
webMc: image: itzg/rcon environment: RWA_USERNAME: admin RWA_PASSWORD: admin RWA_ADMIN: "TRUE" # is referring to the hostname of 'mc' compose service below RWA_RCON_HOST: minecraft-kingdom-survie # needs to match the RCON_PASSWORD configured for the container RWA_RCON_PASSWORD: "demo" RWA_RCON_PORT: 25575 ports: - 4326:4326 - 4327:4327
any idea ?
As far as the RCON_PASSWORD generation, I am not able to recreate that part of the issue. Creating a container with
> docker run -it --rm -d --name mc -e EULA=true -e RCON_PASSWORD=demo itzg/minecraft-server
and then checking the properties file shows the requested password:
> docker exec mc cat server.properties | grep rcon.password
rcon.password=demo
I just tried a fresh instance and the example still works fine for me https://github.com/itzg/docker-rcon-web-admin/blob/master/docker-compose.yml
Just as an update I have never got this to work on my home configuration. I used your default compose configuration and it has never worked. It looks like the web rcon connects:
[16:59:35] [RCON Listener #1/INFO]: Thread RCON Client /172.28.0.2 started
But the screen is just blank (I used to get the error of "perhaps it is down". So an improvement but still not working. I am about to just blow my entire docker install away and retry.
I just completely re-installed docker and removed all volumes and images and still does not work. There are not even any logs in the rcon container to TS. So if anyone get's it to work would appreciate and tips you have.
I had issues running this docker image for the longest time as well. I did not realize that both ports 4326 and 4327 need to be available to get the WebUI to work. Using F12 / looking at the web console it will throw an error every few seconds that it can't connect to the 4327 port if you access the webpage over 4326. Port-forwarding / allowing both ports access to the browser fixed it for me
