Lost connection to RPi 3 / Roon Bridge

Server: Mac Mini M1 with Sequoia 15.3
RPi3 with rooExtend + Roon Brigde + rooNuimo connected wireless.
I suddenly lost connection to the RPi3 (was under Sequioa 15.2.
I updated to Sequoia 15.3, connected the RPi3 by Ethernet and reinstalled Roon Bridge. I reinstalled licence for rooNuimo and I can see all this in the extension section.

Here my problem: In the audio settings I do not see this RPi3 as an endpoint, so I cannot play music to this endpoint.

I checked the privacy and security settings for Roon and Roon server (toggled off and on and restart). But no show.

Any tips are highly appreciated.

P.S. Is this right that I do have Roon and Roon server or should I have only Roon server?

Is the DAC powered up?

Yes it was, but facepalm USB connection got loose.

Thanks. :grin:

“That was easy!”
