I own a SB Duet and a SB Radio.

I run the music via a QNAP on SSOTS version 4.9.1 with SBS version 7.5.1-30836

I have the latest firmware on SB Duet and Radio.

But only the Duet makes contact with my SBS, I only get connection errors when I try it via the Radio. The Radio has contact with my squeezebox. I try to setup a SBS on my pC (next to my NAS) and that one can be found by the radio.

Any ideas how to fix that I can contact with the SBS on my NAS.
