Hi @Nick_Rossman,
Thank you for your patience.
We’ve taken a close look at the diagnostics that reached our servers last week. Logs show the Roon app failing to retain a handshake with the broker; there are broader failures with network discovery, particularly after the phone wakes up.
For due diligence, I’d first ensure that the Nighthawk router IGMP snooping and multicast forwarding enabled. That should be detailed on page 61 here: https://www.downloads.netgear.com/files/GDC/RAX200/RAX200_UM_EN.pdf
From there, please visit some of the workarounds in this thread. Let us know if this is helpful. We’ll watch for your response. Thank you!
