What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

NUC has Static IP
I have static/permanent IP with my provider
Port 56000 is forwarded to NUC’s static IP
UPnP is off (on makes no difference, and it has worked with UPnP off before)
Roon report ARC “Ready”
When starting ARC on iPhone, it keeps searching for Roon server, both on wi-fi and outside the home.

I’d uninstall arc on the phone and install again.
