I’m running Mopidy on a Pi 3B+ and so far it works fine when accessing it remotely. From any computer on the same network as the Pi I can access Iris and play music and it all works.
I can launch a browser on the Pi itself and access Iris, but when I try to play a track nothing happens.
I’ve checked the logs with sudo journalctl -u mopidy and I see these errors happen whenever I try playing a song:

I plan to use the Pi as a music player in a non networked environment, so having Mopidy accessible directly on the Pi is kind of important.
