Localhost:8080 - connection refused

Hi, I spin up my docker with:

docker run --network host -p $PORT:$PORT --env-file ./env_file -v $(pwd):/home/node/app $PROJECT_NAME:latest

And I see it running in the Terminal as well as in the Docker UI.
But when I try to open localhost:8080 in the browser I get Connection refused.
Nothing else; also since it doesn’t connect no logs or so in the container itself.

Any ideas?
Thank you very much for your help!

I removed --network host
