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.
In order for Roon’s @support team to better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they can have a clear understanding of how your devices are communicating.
Do checkout the link that @Geoff_Coupe posted, it should resolve the problem… do let us know how you get on.
