      Yeah, maybe its my isp doing something weird which usually passes, but fails this one.

      I tried turning up logging and adding this to the option box (nothing else in it)

      server:
      log-queries: yes
      log-replies: yes
      

      Sometimes I get the timeout:

      [2.5.0-RELEASE][root@slottet.doff1]/root: dig www.broadcom.com
      
      ; <<>> DiG 9.16.12 <<>> www.broadcom.com
      ;; global options: +cmd
      ;; connection timed out; no servers could be reached
      
      [2.5.0-RELEASE][root@slottet.doff1]/root:
      

      With these entries in the log:

      Could the issue somehow be ipv6 related? Since my isp doesn't deliver ipv6?

      It's missing the 'ad' flag!

      I can't find anything in the log for this, but i guess it's because google resolved the address, and not my resolver.

      Could this be an ipv6 related issue? maybe a configuration fault on my side?

        If you have no IPv6 - why would it even try to talk to an IPv6 server?

        You could try setting
        do-ip6: no

        In your options box.. But it shouldn't even try if you don't have ipv6 on your wan..

        That makes no sense to me - unless all you got back for some NS was an AAAA

          First things first : I just generated a new 'DNSSEC' report, as the latest on dnsviz.net was 3 months old :

          https://dnsviz.net/d/broadcom.com/YGFlsg/dnssec/

          which doesn't show a nice clean result.

          @stoffix said in Sporadic dns issue related to DNSSEC:

          ;; connection timed out; no servers could be reached

          unbound getting restarted by an incoming DHCP lease ?

          Check the resolver log : how many time it restarts per day ? hour ? minute ?
          Just to be sure, uncheck :

          35e86b74-73dc-472d-856e-c01e79e7e5de-image.png

          Btw : I did a new test on dnsviz.net, 2 minutes later.
          https://dnsviz.net/d/broadcom.com/YGFoPg/dnssec/
          This time : no red 'fatal' error messages - just 4 warnings. Looks like they are in the middle of some KSK shift.

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

            No because I updated it when I did it - so not sure how that was possible.

            But yeah failure to talk to someone is not a dnssec failure..

              dhcp registration was on, i've turned it off last night.
              At the moment the log fills so quicly i can't see how often it restarted, but it's off now anyway. Thanks.

              my options box now reads:

              server:
              log-queries: yes
              log-replies: yes
              do-ip6: no
              

              My wan is a pppoe, and I don't have a public ipv6 address. I checked the interface status page and for my wan it shows a link-local ipv6, maybe that's why the resolver was trying ipv6 as well?
              For now dig only seems to show a timeout checking www.broadcom.com
              I got some more detailed logs from the resolver in the attatched file: log.txt
              It's too large to write it in the post.

              Some entries looks interesting:

              Mar 29 14:57:42 	unbound 	99799 	[99799:1] debug: not validating response, is valrec(validation recursion lookup)
              

              And the responses I see in the log doesn't show the 'ad' flag either.
              If I should guess it looks like unbound is unable to validate (dnssec) www.broadcom.com by not getting some query responsens, and therefore timeouts while waiting for said responses. It looks like unbound keeps trying for a little while after dig gives up -not that it makes a difference.

              Could there be an ipv4 specific issue somewhere?
              Or maye a "geographical" issue? (I'm located in northern Norway)

                Possible - when you resolve you have to talk to the authoritative nameservers for a domain or tld, etc. So yeah its possible that isp peering issues, or just geographic issues related to latency could cause pain in resolving.

                So if unbound has issues talking to specific NS returned, then it should try not to talk to those and choose more the NS with better response times, etc. But if your cache was clearing all the time because of unbound restarts.. Then it wouldn't know which ns it was having issues with, etc.

                Now that you have unbound not restarting all the time, see if you settle down for resolving that fqdn.. You can always look up details of how a specific fqdn would be looked up.

                BTW - you might notice I have no ipv6 ns in the infra cache, because I have no-ip6 set as well.. Was playing with that from another thread a couple days back.. And hadn't yet removed it..

                  It's interesting that you have no-ip6 set as well, since we shouldn't percieve any difference then.

                  When I look up the cloudflare fqdn It's almost letter by letter the same as yours:

                  The only differences I notice betwenn dnssec support enabled/disabled is some of the rrset digits are different.
                  Could it be an issue with "my" nameservers?

                    Ah you had them cached, mine didn't so it just listed the NS it knew about that it would need to talk to to look that up.. Once I actually did a query for it, then the actual ns would be listed.

                      I (spending way too much time) found out "tother 3" means timeout other and 3 is the maximum value.

                      I guess there's not much more to do/find out about this. If the problem escalates I'll just have to turn off DNSSEC, at least now I know where to look.

                      Thank you for all your help!

                        tA and tAAAA and tother should all be zeros.. If they are not - then your having problems talking to that NS.. either network issues, or it just sucks as a NS and isn't answering.

                          Hopefully it just sucks as a NS, since it works without DNSSEC and I don't want network issues!
                          It's been a great learning experience. For now I keep DNSSEC on, and have an exeption for broadcom and turned off ipv6 in unbound as you suggested.

                            Them pointing cname to cname isn't best practice either. While its allowed - it causes extra lookups..

                            ;; QUESTION SECTION:
                            ;www.broadcom.com.              IN      A
                            
                            ;; ANSWER SECTION:
                            www.broadcom.com.       300     IN      CNAME   cdn.broadcom.com.
                            cdn.broadcom.com.       3600    IN      CNAME   www.broadcom.com.cdn.cloudflare.net.
                            

                            If they want www.broadcom.com to point to www.broadcom.com.cdn.cloudflare.net.

                            Then they should just do that, but they are pointing to cdn.broadcom.com first, which then points to the cloudflare.net cname..

                            Its not efficient to do that.. Just causes extra work..
