Firefox, PopOS, NextDNS no TLS?

Hi all.

I use PopOS 22.04, the most current Firefox and downloaded and installed nextdns on my system.

I see a green dot in the WebGui of nextdns under setup. I also see the log is most current. My firefox shows that I use nextdns and it also says that I have enabled https-only mode.

I went to https://www.cloudflare.com/ssl/encrypted-sni/

and it says I don't use TLS.

So now I am confused... Do I use tls or not. Or is DNS over HTTPS? I am confused.

Please help

Thanks

    That page only tests against Cloudflare's own DNS service, specifically, it will say you're using Secure DNS if you're using either Cloudflare's DoH/DoT, which each have a specific subdomain only resolvable through the service. If you want to test what NextDNS config you're using just visit the NextDNS dashboard.

    For the inevitable pedant, the Cloudflare test will also say you're using secure DNS if you're using an unsecured DNS config as long as the eventual upstream is Cloudflare DoH/DoT.

       Thanks a lot. I have read that Cloudflare tests your DNS as well but only for DNSSEC and TLS. Not for Secure SNI and Secure DNS.

      And it showed DNSSEC as active. I could not find where NextDNS shows me if the connection is encrypted.

      Anyway: I found my error. I blocked a domain which cloudflare uses to test TLS. Allowing this domain shows me I am using TLS and DNSSEC.
