Why is no one using Quad9 instead of Cloudfare?

iPhone > Safari webkit > WireGuard tunnel home network > PiHole DNS (Quad9 upstream) > WireGuard tunnel ProtonVPN endpoint

That is the flow of my current network.

Edit: I ran curl from my server

Can confirm my PiHole is resolving the requests and forwarding them to Quad9.

wow. uh okey, quite a complex setup. But in this specific case it’s not even reaching Angie Guardian… Let alone Angie/Nginx… It fails clearly at TLS handshaking and the non-TLS is unclear why it fails.

Here is an example if what I would have expected using curl via httpS:

curl -v https://angieguardian.org/
* Host angieguardian.org:443 was resolved.

* TLSv1.3 (OUT), TLS handshake, Client hello (1):

*  CApath: /etc/ssl/certs

But your non SSL is maybe even more interesting… since that is also failing (port 80 has NO angie guardian protection btw), here I would expected the following:

curl -v http://angieguardian.org/
* Host angieguardian.org:80 was resolved.
* IPv6: (none)
* IPv4: 77.61.56.117
*   Trying 77.61.56.117:80...

TDLR; clearly something else goes wrong with this setup.
