Sonos things offline since last (Sonos) update

More as a warning than a call for help: My devices updated to firmware 81.1-58210 two days ago and have since been shown as offline in openHAB (current version 4.2.2 on Debian 12). In openhab.log i found only these entries:

My devices are using this firmware, too. I don’t have issues in openHAB (4.2.2).
But i have no idea, whats wrong, sorry.

Have you tried to deactivate and then reactivate the things. Perhaps it helps.

My Sonos One has also been ONLINE since the latest update, although I had to roll back from OH 4.2.2 to 4.2.1 for an unrelated issue.

Solved those by restarting openHAB, pause/resume the things didn’t help.
