John, I’ve split your post out of Volker’s Support request to make a new one. Even though it sounds like like same issue, Support will want to track it separately.
The Roon @support team prefer one topic per customer’s issue… so they are able to track it and focus on each individual problem. Hence I split out your topic.
Please provide a brief description of your current setup and the nature of the issue using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they have a clear understanding of how your devices are connected.
