Nighthawk iOS app device access control issues

[Sandman0]

I installed a Pi-hole on the network and now when I’m connected to wi-fi The Nighthawk app isn’t seeing attached devices properly. I discovered this when I wanted to disconnect a device that is normally on the wireless for a couple of hours while I made some changes. To be clear here everything works fine if I disconnect from my Wi-Fi. It’s a really weird issue, it sees devices on the wireless network like in the attached screenshot when the Pi-Hole is active, but shows everything fine if I connect from outside the network.

Anybody know what domain(s) I need to whitelist in the Pi-hole to get this working correctly again?

And what Netgear device are we talking about here?

It’s an R7800, which is working fine, it’s the Nighthawk app I’m having issues with.

Yes I looked through 10+ pages of search results in the forum and found nothing even remotely close to what I’m looking for.
