I am not able to Resolve a specific DNS Name on 1.1.1.1 server. When I dig for the address specifying Cloudflare’s 1.1.1.1 I got no result, but if I specify another DNS provider, e.g. 8.8.8.8 it resolves as expected.
See, I am able to successfully resolve any other DNS Name via 1.1.1.1, the error is only with this specific subdomain.
I was trying to solve an issue as to why all my Nest products stop working when using Cloudflare nameserver, but works on the google nameserver. It turns out that Cloudflare doesn’t resolve the CNAME properly and this is the exact same issue as the OP reported here.
Its been fixed now. Not a Cloudflare issue but a amazonaws issue. I also had issues with nest equipment. I narrowed down to an issue with compute-1 .amazonaws .com
dig compute-1.amazonaws.com @1.1.1.1 NS
