[SOLVED] Sonos Binding no updates in OH2

Hi i have the Sonos binding already installed since some time now but was only looking into it recently again.
when i setup everything worked as expected but recently no items are getting updated. if i for exsampe changing a radio station, its not getting updated in OH2. however if i change the station in my Habpanel its also getting updated in the sonos App and its working.
but all other items are also not getting updated, like artist, album cover, title ,…

in the log i see only entries like the below

any idea what that could be?
running latest stable OH2 (2.2.0)
