I too am encountering issues as recently as yesterday morning (10/31) where the API server simply goes out to lunch. I do a restart. It hangs for sometimes a minute or two up to 10+ minutes and then works for a while, repeating the same go to lunch issue. I rinse, repeat on the restart and wait time. I had to do this at least 10 times yesterday. Because the API server wasn't stable, I was using jukebox to launch shuffled playlists. That too stopped a couple of times mid-playlist.
