NAD C658 Roon Ready isn't recognized any more

ROCK suddenly stopped recognizing my NAD C658 Roon Ready streamer DAC.
It only recognises it vía AirPlay. I ve tried cleaning cache, rebooting etc …without success.

Possibly this issue?

It seems that’s the case, because I factory reset the NAD C658 yesterday.
Thanks
