connection refused accessing minecraft from another host

[BigMichi1]

Hello,

after adding the copying over the example Minecraft configuration from here https://github.com/MitchTalmadge/AMP-dockerized/blob/master/example-configs/minecraft/docker-compose.yml and running docker-compose up -d on my root server the container starts successfully and the UI can be reached like normal. After setting up the Minecraft configuration and starting it everything looks ok.

now the problem is when trying to connect to that instance from a different host like my desktop PC the connection can not be established.

Does anybody have an idea or suggestion what might be wrong with the setup?

so I was checking the availability of the ports directly on the root server by using nc and netstat

Checking docker mapping

docker-compose ps shows

I found the issue. as I'm using the Bedrock edition the 25565 ports needs also to be a UDP mapping in the docker-compose.yml file. After changing that and restarting the container everything works now. Thx for this amazing docker image
