When I try to do grouping functions this error appears in the log, ofter repeatedly. The IP address of the Beam is confirmed correct. When I use a different speaker the error repeats itself (with any speaker) by citing the corresponding IP address I use.
It should be noted that the Sonos command creating the error still seems to work, most of the time, even when the error is given. But Sonos functions seem unreliable and I wonder if this error points to a reason why.
There was a moment when Sonos worked with no visible errors but then after a reboot more red like this.
Any ideas?
