Not really a docker pro, but i had an issue recently when in the container my service was run on “localhost” instead of “0.0.0.0”.
You could try in the ‘docker-entry.sh’ file of ors to adjust it and see if the services can connect. But that’s only a wild guess. (so ‘localhost’ -> ‘0.0.0.0’)
network:host from your issue: https://docs.docker.com/network/host/. It just means the docker container does not have to be mapped to a port on the host (using e.g. `port: “8080:8082”) but already uses the defined port on the host machine if it’s free (e.g. 8082 in above example)
