The problem

When trying to add Music Assistant server to Home Assistant, I get an ambiguous "Failed to connect" error message.

What I have verified:

• MA server is running and i can access it at :8095 from a remote PC
• The HA container can also access this

When I restart Home Assistant, the MA server will show up in the "discovered" section with the proper url and port. However, clicking submit returns the same error.

Setup Main OS: Fedora CoreOS

• Home Assistant running in a container via podman (using default bridge network).
• Music Assistant server running in a container using host network and privileged as instructed podman run -d --network host --privileged -v mass:/data ghcr.io/music-assistant/server
• Added MA via HACS

Upon restart:

Manual addition:

How to reproduce

Spin up HA container

podman run --name home-assistant -p 8123:8123 --cap-add=NET_RAW --cap-add=NET_ADMIN -v ha_config:/config:Z homeassistant/home-assistant

Spin up MA container podman run -d --network host --privileged -v mass:/data ghcr.io/music-assistant/server

Add HACS to HA:

// Enter container
$ podman exec -it home-assistant /bin/bash

// Add HACS
$ wget -O - https://get.hacs.xyz | bash -

Add MA

Turns out this was an issue with CoreOS and podman. Podman does some dark magic with networking and requires containers to be in a pod to communicate. Even if you put them on the same bridge network when starting them, it still won't work.
