Hi @Jos_Brands,
Thanks so much for taking the time to write in and share your report. As it stands in your setup, we’re unfortunately not able to provide Roon support on the Rhein products. I feel it important to inform you that this server device you are using is unlicensed with Roon. Because of this, we’re not able to offer support as it’s unfortunately an unsupported device.
That said, there are others on community that may be able to provide additional troubleshooting steps for you. I’ve moved your thread over the Tinkering for this.
Thanks for your understanding, I am confident you’ll find additional resources from others in the community.
