      Looking to use the Cloudflare DNS for IPv4 and IPv6, I have them in the general setup:

      1d13a354-d0a8-45cb-9445-8381daa23a03-image.png

      And in the DNS Resolver I forward them and use DNSSEC and SSL/TLS:

      0e141fab-dfc0-4695-a6bc-9dc21c13cfd5-image.png

      Doing an IPv6 test it said I did not have IPv6, what would be causing this and what do I need to do to make it work.

      Thanks!

        does your provider use IP6? do you have your pfsense setup fully for ip6?

          Do you actually have an IPv6 address on pfSense?

          PfSense running on Qotom mini PC
          i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
          UniFi AC-Lite access point

          I haven't lost my mind. It's around here...somewhere...

            Yes my provider uses IPV6 and if I put in the CloudFlare IPv6 DNS address in the DHCPv6 Server it then works, but not if I have them in the General Setup area.

              You shouldn't need to enable dnssec if you're using forwarding mode with cloudflare. Also add the cloudflare hostname to enable hostname verification for the DNS servers. You can paste this in the hostname value for all 4 cloudflare DNS servers that are listed: 1dot1dot1dot1.cloudflare-dns.com

              Also for what it's worth the ip4 DNS servers still return ip6 results. So even if you only have the ip4 servers configured you'll still get ip6 results. Also try https://1.1.1.1/help for cloudflare diags.
