· The device has no problems with another audio source

Have you checked that Roon is whitelisted in any firewalls?

· I've checked the firewall and the issue remains

· My devices are on a single subnet but is not visible to Roon

Do you have a complex network setup?

· Both the device and RoonServer are connecting to a *single router*

Try to disable any additional networking interfaces on your RoonServer machine.

Disable Mac firewall, and reboot everything starting from the router, WiFi mesh, access points, network switches, Mac, Lumin, mobile devices, etc.

Hi @leerwrubel,

Thank you for your post and welcome to the forum.

We’ve enabled diagnostics and the latest RoonServer logs suggest that a Lumin streamer is visible to RoonServer on this network, both as a RoonReady and Airplay Zone. Can you confirm if this is the endpoint in question (do you have any other Lumin device)?

Mesh networks can sometimes interfere with multicast device announcements, depending on the make/model and settings configuration. I recommend checking that any IGMP Proxying and IGMP snooping are enabled, and that any multicast forwarding settings are similarly checked on.

Since you’re hosting your RoonServer on a Mac, make sure that you’ve toggled on Local Network Access for Roon in System Settings → Privacy & Security. I also recommend changing the Private WiFi Address from Rotating to Fixed in WiFi → Details.

Please let us know if this helps! Thanks!
