Cloudflare resolves but Google doesn't. Why?

I am in Mexico. This fails:

% curl -s -H 'accept: application/dns-json' 'https://cloudflare-dns.com/dns-query?name=www.bispebjerghospital.dk&type=A ' | jq .
{
  "Status": 2,
  "TC": false,
  "RD": true,
  "RA": true,
  "AD": false,
  "CD": false,
  "Question": [
    {
      "name": "www.bispebjerghospital.dk",
      "type": 1
    }
  ],
  "Comment": [
    "EDE(22): No Reachable Authority (time limit exceeded)"
  ]
}

but this succeeds: dig @8.8.8.8 www.bispebjerghospital.dk Why? What requirements does Cloudflare require of a domain to resolve its record? The map shown at [whatsmydns](https://whatsmydns.net/#A/www.bispebjerghospital.dk) shows red X's for some locations. EDIT: Marcus in the comments seems to have no issue with the Cloudflare. So since I suspect this is an anycast issue, here are the IP addresses I see for Cloudflare:

% nslookup cloudflare-dns.com
Server:		10.2.9.68
Address:	10.2.9.68#53

Non-authoritative answer:
Name:	cloudflare-dns.com
Address: 104.16.249.249
Name:	cloudflare-dns.com
Address: 104.16.248.249
Name:	cloudflare-dns.com
Address: 2606:4700::6810:f9f9
Name:	cloudflare-dns.com
Address: 2606:4700::6810:f8f9

EDIT2: NS records as requested:

EDIT3: NextDNS succeeds:

EDIT4: I can't query from ns3.region.dk directly:

% dig @ns3.regionh.dk www.bispebjerghospital.dk
;; communications error to 128.0.75.226#53: timed out

EDIT5: Seems like that previous command should have worked, since it works on [dnsexit.com](https://dnsexit.com/it-tools/network-tools) :
