Hi @martin.middelman, and thank you for the tag @UliR!
Unfortunately, Martin, it appears that you’re using a Rhein Z1 device as a Roon Server, which is an unlicensed device and therefore falls outside the scope of our support. You can read a bit more about that here:
I have moved this thread over to Tinkering where you’re free to talk to other users about this issue. We have a robust community of users who I’m hoping will be able to provide additional insight into your device, and hopefully get you into a smoother transition state!
My apologies here Martin! If you’d like to move to a supported server device, I would be happy to continue troubleshooting.
