Minecraft docker-container refuses connection

So I have this Dockerfile:

FROM openjdk:8u212-jre-alpine

LABEL maintainer "cowboy_patrick"

RUN apk add --no-cache -U 
  openssl 
  imagemagick 
  lsof 
  su-exec 
  shadow 
  bash 
  curl iputils wget 
  git 
  jq 
  python 
  tzdata 
  rsync 
  nano 
  sudo 
  knock 
  ttf-dejavu
  
EXPOSE 25565 25565

COPY minecraft /root/minecraft
WORKDIR /root/minecraft


RUN chmod +x /root/minecraft/start_minecraft.sh

CMD /root/minecraft/start_minecraft.sh

This just copies an existing world into an alpine with java and executes some prewritten scripts, I had written for running it on a vps (doing automatic backups etc.)

When I execute it with

docker run –network host -p 25565:25565 –name mcs mcserver

I can see the following in the container-dashboard:
port forwarded

For good measures you can see my console-output here but it’s pretty standard. Just a minecraft-server that boots up.

The only thing I don’t understand is why the connection gets refused when I try to join localhost:25565:
connection refused

Does anyone have an idea on how I can allow this connection? And in extent allow connections from outside my machine (assuming that port-formwarding and everything works).
