I am running the latest version of Pi-Hole (4.2.2/4.2/4.3) on a RPi 3B using Cloudflared w/126.96.36.199. over HTTPS (Custom 1 (IPv4) 127.0.0.1#5053).
I would like to add additional Upstream DNS servers for redundancy (OpenDNS and Quad9).
When I select any other DNS server in addition to Custom 1, a short while later, I get the “Lost Connection to API” warning and everything stops working.
I have tried adding strict-order to a .conf file and seems to work for its intended purpose (putting Custom 1 first), but it doesn’t resolve the lost connection error.
Any ideas for how to achieve my desired setup?
