      @maverickhl What if you uncheck "Use SSL/TLS for outgoing DNS Queries to Forwarding Servers"?

      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

        Wow.. that works... so why? I never had an issue enforcing TLS on DNS queries before? Not with Cloudfare at the very least....

            Does it work if you're not using DoT? Edit: Missed some replies 🙄

            Though that works fine for me using DoT to 8.8.8.8:

            I don't actually see it trying to resolve anything in your logs.

              Which is the problem, nothing is coming up to help me determine the issue. I took a while to get back because I wanted to do the log capture at a time when less people are working so I can capture them. These are the log differences between Cloudflare and Quad9 and the fact it does not resolve in Quad9 at all is very weird.

                If the query answer from " 9.9.9.9#853" is sympathetically "THROWAWAY" you can do 2 things :
                Stop using TLS or even stop using 9.9.9.9.

                You're sure nothing is filtered upstream ?
                I saw

                debug: tcp error for address 9.9.9.9 port 853

                As TLS over port 853 needs TCP, and TCP is bad, then 9.9.9.9 doesn't even receive your request correctly ( ? ) ....

                When the quad9 issues go away (thrown away ;) ) I advise you to look at other threads in this forum. Because this :

                @maverickhl said in pfsense dashboard show "Unable to check for update" via Quad9 DNS:

                Jul 13 12:34:45 dhcpleases 14363 Could not deliver signal HUP to process 45787: No such process

                is also a possible issue, and discussed a lot on the forum.
                It means unbound was in the process of getting restarted - and while it was restarting, it was informed to restart again.
                For now : how often does yours restart ?
                Go to the page and search for "info: start of service (unbound 1.15.0)." and count them.
                How many a day ? per hour ? even more ?

                No "help me" PM's please. Use the forum, the community will thank you.
                Edit : and where are the logs ??

                  Still not seeing any logs for info: resolving. Everything in your logs appears to be reverse lookup for PTR. So I'd suggest it's not using Unbound for those lookups. Something is not configured as you expect it to be.
                  However even if that is that case it's hard to explain why pkg update works but the dashboard check does not.
                  Try to resolve ews.netgate.com in Diag > DNS Lookup. Make sure all the defined servers there can resolve it.

                      Mmm, so exactly what settings do you have in System > General Setup and in Unbound?

                        Nothing fancy, but here are the main things I have setup:

                        System General Setup:

                        Added DNS 9.9.9.9 and 149.112.112.112

                        Set DNS behavior to Use Local then remote (default)

                          Hmm, the only thing different I have is the custom entry you have:

                          server:
log-queries: yes

                          But I see all the queries logged so I suspect you may have created a conflict there. Try removing that.

                            I do think it is Quad9's issue and mostly likely regional. I had to send a few DNS resolution request for their upstream provider to fix since some websites were not resolving but was apparently accessible based on their domain checker.

                              Hmm. Weird that it's not showing queries in unbound though. Seems like however it's failing could be because it's not going via Unbound...
