      I started to notice this yesterday, but today Cloudflare (1.1.1.1) stopped resolving external DNS.

      Has something changed with Cloudflare and pfSense 2.4.3? I had to change my primary DNS (General>DNS Servers) to 8.8.8.8 to get external DNS to resolve correctly again.

      Cloudflare has been working flawlessly until today using the instructions posted here:

      https://www.netgate.com/blog/dns-over-tls-with-pfsense.html

      Any guidance would be appreciated.

      Thanks,
      Brent

        try this other #Cloudflare DNS TLS address
          - address_data:  1.0.0.1
            tls_port: 853
            tls_auth_name: "cloudflare-dns.com"

        that address being 1.0.0.1 -  see full list of TLS Servers here -  https://dnsprivacy.org/wiki/display/DP/DNS+Privacy+Test+Servers

        You can and should also check real time status of DNS Privacy Servers as they are experimental and are not always stable - you can monitor DNS TLS Servers Real Time Status here below:

          Assuming you have CenturyLink, it's not related to PfSense - check out: https://www.reddit.com/r/homelab/comments/8jq1u5/centurylink_blackholing_1111_cloudflare_dns/

          It's a CenturyLink issue.  :(

            Indeed, a CenturyLink issue that they have now corrected.
