· The client on my Thrax Enyo no longer works. When I reset the enyo, roon sees the client and it shows up in the audio client list with an private IP address (so presumably it broadcast to roon when it came up), it continues showing with the private IP address for a while, although I can never playback music successfully through that zone, and it will eventually disappear as an audio option. Sequence repeats if I unpluf and replug ethernet or restart. The switch and router are working fine. I can plug other roon ready devices into the same cable and no problem.
Tell us about your home network
· hub ethernet through a patch panel to each room in the house, switch in each room connecting various devices. I'm a network guy, network itself is functioning fine. Also note that even after the Thrax has been turned off and disconnected from the network, it is showing up as a zone to stream to in the roon application (although it no longer appears in the list of roon zones in the Audio Setup screens).
Looking at the Nucleus logs, we can see that this erratic behavior is actually being triggered by the Thrax unit itself. The logs show that the Thrax is unexpectedly dropping the TCP sessions and then repeatedly trying to reconnect to the Nucleus using new ephemeral ports. The Nucleus is simply reacting to these drops and waiting for the Thrax’s RAAT module to broadcast itself again.
Since your general network is functioning fine, let’s isolate the Thrax’s network interface to be absolutely sure.
Could you try bypassing the patch panels and room switches entirely? Please connect both the Nucleus and the Thrax directly to your main router using standard Ethernet cables.
If it works flawlessly: We can look into switch configurations (like IGMP Snooping, STP, or physical link flaps on that specific switch port).
If it still drops the connection: Then the issue is 100% isolated to the Thrax's internal network module or its OS. If that happens, your best bet would be to perform a full factory reset on the Thrax unit, or check if there is a way to reinstall/update its firmware to refresh its network stack.
Thanks, I hunted it down; for some reason STP was activated on this subnet and was interfering with the Thrax’s initial DHCP requests. The Roon Core could see and talk to the private IP address but it wasn’t a path to receive music through. I resolved by turning off STP in that segment. Working fine know.
