Roon ARC - Nucleus Core isn't Configured

It looks like you’ve got a double NAT situation. Basically you have both the Technicolor Router and the Google Nest WiFi acting as a router. The easiest solution would probably be to see if you can set the Technicolor Router to something like “bridge mode.” Alternatively you could put your Google Nest into bridge mode.
