Description of Issue

In ROON running on my PC PS audio is working fine.

Today I have installed Roon on a NUC (Roon Rock): it sees PS audio, but systems says certifcate is not

What is wrong? This (below) is the message when selecting PS audio when I use NUC with Roon:

Translation: there is no valid certificate

Below a screenprint when I use Roon installed on my PC: no certificate, but PS Audio is working.
