Hi Tiiffi

I want to ask you a question regarding my minecraft server by using docker

I have packaged two MC server (MC 1.16.5 and MC forge 1.12 )image by using docker
I already set up the rcon command in server.properties of two server.

one set up as :
rcon.port=25575
rcon.password=XXXXXX
enable-rcon=true

the other set up as:
rcon.port=25574
rcon.password=XXXXXX
enable-rcon=true

Then , I use mcrcon , but the program always show "Connection fail ".

I am not sure where the question is.

Sincerely,
Charlie

Using the tool for a similar feature, i've come across "Connection failed" as well, came here looking for answers, wondering if it has been deprecated.

Edit: It's working as intended

Are you connecting from a different mashine or the localhost? If you try to runn it from a different mashine, you need to check if the rcon Ports are allowed in the firewall of the server. Maybe even check if the Docker may block the request.

I just ran into this as well. My solution was port publishing port 25575 to the host. The issue is while the docker container might be listening on port 25575 the host is not. You have to tell Docker to listen on that port. https://docs.docker.com/config/containers/container-networking/#published-ports
