Connection information incorrect for "https://cloudflare-dns.com/help/"

When I run the Cloudflare’s "“https://cloudflare-dns.com/help/” it tells me that Using DNS over HTTPS (DoH) is “yes”. but If I change the local host DNS on my mac OS to 250.250.250.250 a fake DNS so I can observer Firefox performing DOH resoultion of web sites it does not work. No web site is resolved.

Which means Firefox is defaulting to my workstations DNS and not using DNS over HTTP even though it is configured. Below is the connection information.

#2

How did you configure it on Firefox? In about:config, I search for ‘trr’ and set network.trr.mode to 3 (DOH only)

#3

I believe the first ever request of DoH request, needs to rely on your machine DNS config. So that your machine knows the IPs of cloudflare-dns.com or mozilla.cloudflare-dns.com

https://cloudflare-dns.com/dns-query
https://mozilla.cloudflare-dns.com/dns-query

If you use the DoH address below does it work?

https://1.1.1.1/dns-query

That was my initial thinking as that would make sense to make the default entry in firefox https://1.1.1.1/dns-query but Firefox default entry is " ```
https://mozilla.cloudflare-dns.com/dns-query

I also did a "whois" lookup using my Mac's built in app for 1.1.1.1 and got the following resultsServer Name: 1.1.1.1
