Not sure whether to post this here or on the Discord server. The only category I'm allowed is Bugs but I don't know that this is a bug.

Briefly, I have a Model B+, and I read that others are using the B+ for pi-hole. I've tried different OS installations, but currently the B+ is running Buster Jan 28 2022 (lite).

I've done the install you provide (curl -sSL https://install.pi-hole.net | bash) without incident and it seems to install just fine; however, pi-hole is non-responsive. I'm using a static IP on a wired network (Ubiquiti UDM); the installer detected this and I selected all default prompts. The IP is 192.168.69.69, and this is the only IP address on this network, as configured in my UDM.

I can ping the B+ just fine, but when I point any queries at it, I get nada (see below). What's my next best troubleshooting step (go to Discord?). One thing I note from the admin interface is that the although the load looks ok (below 0.5 typically), the RAM utilization is only 14.7%. Based on other forum posts I've read for the module B+, this doesn't seem correct (very low). Screenshot attached.
