I can see my library and select songs/albums for playback, but nothing plays. If I select a song nothing happens. If I select an album, it cycles through the songs on the album and nothing plays. I can go directly to same music folder that the Plex music library accesses and play the same content back with no issue.
That sounds like the symptoms of a router that doesn’t support NAT loopback. It’s a known issue that we’re working on addressing.
same problem for me, everything shows up but nothing plays
