DNS over TLS issues with Resolver



  • Good Morning all,

    I have started trying to use DNS over TLS with quad 9 as my DNS provider. There is an issue that I am seeing where certain sites do not resolve correctly versus when using Pfsense as my DNS resolver(local unbound resolver). Below is my setup under general
    5457c490-a95f-4fbc-8f7d-5accca4890a1-image.png

    Then we have my DNS settings

    My LAN rules are as follows (leaving the port 53 rules up and active as I am testing, so switch between local and quad 9 DNS)

    And below is what comes out for this specific site

    f46baafa-7c2e-4074-9db1-bdce6ed51335-image.png

    This is what shows up in the logs for DNS when I reload the page

    Any help or insight as to why the page correctly loads the images when using local DNS for unbound vs quad9 ( also happens when using cloudflare and google DNS)? Thank you in advance.

    EDIT: added the logs for when local Pfsense DNS is used on the same site, and the images load correctly on the site

  • I don't know if this is going to only be temporary or permanent fix, but for the specific site, putting cloudflare DNS first helped it. It seemed that the quad 9 had an issue trying to resolve the site.
