1.1.1.1/help not showing I am using DoH, when using my DoH endpoint

I am testing my DoH endpoint and wanted to see if Cloudflare notices that I am using DoH. From Firefox I can see that my queries are TRR ‘True’, but from 1.1.1.1/help I see ‘No’ for Using DoH… any insight on why this would be? Is this because it’s only checking for the cloudflare doh endpoint?

“using DNS over HTTPS” is a little misleading, there’s no standardized way to check if the browser is using a DoH endpoint. Since CF runs the resolver, they do some magic with DNS resolution (in the form of DNS hostnames that only resolve when using DoH) to check if you’re using DoH, but it will only work when on 1.1.1.1.
