Description of Issue

Hello, my iPad and iPhone can no longer find my Roon Core. Nothing has changed that I know of. I can access Roon via my Mac, which is connected via ethernet, as is my Nucleus.

I have rebooted everything to no avail. I can access Nucleus via IP address and is says everything is OK.

Any ideas on how I can get phone and iPad to reconnect?


The described symptoms suggest a WiFi related routing (IGMP snooping) issue.

Did that include the network router?

No, I will try that now, thanks.

OK, that’s embarrassing :flushed:.
Rebooting the router worked. Thanks very much.
