Networking changes introduced in Docker 4.1.x and forward on Windows and MAC stop the direct use of the internal docker host IP returned by the docker run --rm --net=host eclipse/che-ip process. On Windows and MAC host.docker.internal needs to be used for internal connections between containers on separate docker networks.
host.docker.internal has been available on Windows and Mac since Docker Engine version 18.03 (March 2018). Support for host.docker.internal on Linux was introduced in version 20.10.0 (2020-12-08), but it does not run out of the box yet (as of Docker Engine 20.10.11 (2021-11-17)). You need to add --add-host=host.docker.internal:host-gateway to the docker run command in order for it to work.
