Moode 4.3: Can Pair but Connect Fails w/ `connect error: Permission denied (13)'

[Drewt]

I am running Moode 4.3 and have rebuilt it twice from scratch and both with the same result: 
I can Pair a bluetooth device (UE Boom 2) but I get the following in syslog when I try to connect. Using `tail -f` the mpd.log registers nothing. It was working and then I mucked around in the BT config

Code:

Oct 15 06:30:11 moode systemd[1]: Stopping Music Player Daemon...
Oct 15 06:30:11 moode systemd[1]: Stopped Music Player Daemon.
Oct 15 06:30:11 moode systemd[1]: Started Music Player Daemon.
Oct 15 06:30:14 moode bluetoothd[1113]: connect error: Permission denied (13)
Oct 15 06:30:14 moode bluetoothd[1113]: a2dp-source profile connect failed for 88:C6:26:92:D7:9B: Device or resource busy
Oct 15 06:30:19 moode bluetoothd[1113]: connect error: Permission denied (13)

I am not sure where to look for a hint as to what the problem might be. 
Any hint would be appreciated.
