piCorePlayer stops playing Spotify song after 1 track

I am trying to play music via PiCorePlayer and RPI3B+ and a PiDesign 502Dac

I have the latest Squeeze Server and PiCorePlayer software.
Spotify via Spotty stops playing after 1 song.
Squeezelite playing my local NAS music via SqueezeServer is OK.

I also tried Max2Play and it works fine via Spotify(Spotty) and Squeezelite(Local NAS).

I have configured most of the settings from this site:

Any help please.
