Plexamp: The player <random_string> wasn't found in available resources

My freshly installed Plexamp won’t play :frowning:
It fetches the list of whatever’s available in the library but there is no audio.

Found this in the Application.log:

Any ideas? Would love to use Plexamp rather than a browser window… A great idea whoever came up with it!
Thanks

The Server.log file will contain more specifics on playback.

Any chance this is new music library? We’ve heard of issues playing when the library is busy building.
