Thanks for looking into this for me. I have been using the setup for several years, without any issues that were not self resolving. However, this one is persistent. It started a couple of weekends ago. Tidal app works fine, both on PC and mobile on this network.
Roon core running on Windows 10 pc, 64 bit.
PC hardwired to ethernet switch >switch hard wired to router
‘Nad node 2 hardwired to another ethernet switch in my listening room, that switch is hardwired to router
Google cast devices, wireless to wifi on router
Hope that is sufficient info. If not, let me know what else you need
