• Bug report ID Pull request mpd + ympd -- ympd web says 'not authorized' / ympd logs show fail to connect by k3ninho · Pull Request #7986 · MichaIng/DietPi · GitHub

Steps to reproduce

1. Install fresh MPD and ympd
2. Confirm MPD OK by playing music from any other MPD client
3. Attempt to control MPD via ympd’s http://diept:1337/

Expected behaviour

• YMPD’s web tool says ‘connected’ and then shows MPD library and current play queue

Actual behaviour

• YMPD Web says ‘connected’ once, then all other actions have a status block ‘not authorized’
• YMPD’s log files show `MPD connection: no such file or directory / MPD connection failed.

Extra details

• The MPD suite is socket-activated by systemd but the ypmd.service file depends on ympd.service and not ympd.socket. Changing the ympd.service dependency so that ympd service runs only after systemd has created the required /run/mpd/socket file allows ympd to connect and control the mpd service.
• I’ve made a PR for this small change.
• Thanks to the community and to Micha for this great project.
