I restarted the router to no avail. I disconnected the hard disk, restarted Macmini. Moved sqlite db. Connected harddisk again. Had Audirvana build up a new library. Restarted Remote on iPad and iPhone.
Again just the ‘Loading…’ message, despite the fact the Remote indicates the track playing and Remote can control (start/pause) the track playing.
Looking forward to any other suggestions
[Edit: I just tried Remote on iPhone with my iMac, same problem: just the ‘Loading…’ message]
