Spotty: One Player isn't listed, all others are

Hi,

I run multiple squeezelite clients with one LMS, unfortunately one player (player2, of corse the most important) isn't listed in spotify. I checked player settings (spotty) as well as the spotty section in "advanced settings". As soon as I tick on spotify connect on other players, they get listed immediately - not for this specific one.

It is - like the others - a Raspberry Pi 2 with squeezelite 1.8 and latest GIT (v1.9.0-1098). I also tried to reset the player settings without success.
LMS was on version 7.9.0, just updated to 7.9.1. Spotty is Plugin

The helper processes are listed as expected for all squeezelite players:
/var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins/Spotty/Bin/i386-linux/spotty-x86_64 -c /var/lib/squeezeboxserver/cache/spotty/b827eb407b2d -n player1 --disable-audio-cache --bitrate 96 --player-mac b8:27:eb:01:02:03 --lms 192.168.0.1:9000
squeeze+ 27248 0.2 0.0 18716 1820 ? Sl 11:24 0:00 /var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins/Spotty/Bin/i386-linux/spotty-x86_64 -c /var/lib/squeezeboxserver/cache/spotty/b827eb85f497 -n player2 --disable-audio-cache --bitrate 96 --player-mac b8:27:eb:02:03:04 --lms 192.168.0.1:9000


I have no glue where to look for the reason of this behavior. Has anyone an idea of what's going on?


kind regards
