      Here is the port 53 UDP traffic when running the dig feedly.com +trace command

        Open that up in wireshark and you can see way more info on what is being asked, what is being returned... See my edit above post.

        But for example, you see that query to 192.33.4.12 that is one of the root servers.

        ;; QUESTION SECTION:
        ;12.4.33.192.in-addr.arpa.      IN      PTR

        12.4.33.192.in-addr.arpa. 10800 IN      PTR     c.root-servers.net.

          So that would suggest that things are working right now? Which is good. I will repeat this traffic capture once things go south again.

          I have installed Wireshark, but am not sure how to get my traffic into it from the text file I have. Any pointers there?

            Not the text that is shown, the download button.

              Great - got it. Now how do I edit out my ip address prior to posting the output? There does not seem to be any replace function in the UI that I can see.

                NVM - figured that out
                Here is some of the output from the capture I posted above

                  It's a little hard to read the image, but there do appear to be successful queries to the root servers, as expected. So I will repeat this capture once the domain question stops resolving, to see if there are any differences in the traffic.

                    Exactly the big question is are you actually sending the queries and just not getting an answer.. Or are you not sending them at all..

                    If it was just something hung up in unbound, you would think a restart of it would fix it... But your having to reboot... Which makes less sense unless its something with the actual wan connection.

                    You should always know the IPs of the roots, because you don't have to query for them - its in the hints file.. So you should always be able to query for IP of a root server even if no wan connectivity..

                      @johnpoz said in Strange issue - not sure how to fix:

                      unbound-control -c /var/unbound/unbound.conf lookup .

                      Yes, when I run those commands, I get very similar output to what you posted, as I should. So I will wait for the next time that domains stop resolving, and run everything again, and then post the results. Unfortunately, I have no idea when that will occur.

                        It happened again and I was able to run the various commands you listed above and perform a packet capture.

                          Did you set that public IP to resolve as local?

                          Where are the queries to and from .com server Servers?.. I only see queries for the root servers?

                          You prob want to set number of packets to capture to 0 vs just the 100..

                            Yes - to obscure my IP address. Wherever it says "local", it originally listed my IP address.

                            Where are the queries to and from .com server Servers?.. I only see queries for the root servers?

                            Not sure. But the packet capture was taken while I ran the command dig feedly.com +trace. I ran it again while trying to browse to feedly.com - results below.

                              That image is too small for me to make out anything.

                              Looks like you have some queries for fox.com - but I don't see anything to the cloudflare NS that are for feedly.com

                                Unfortunately, I can't seem to upload any images > 1 mb, so that one was the best resolution I could use (if you click on it to open in a separate tab, it should be more readable)
                                But it does show DNS queries going out to various name servers. This was occurring while I was trying to load feedly.com (unsuccessfully) and in other tabs browsing to other sites (successfully).
                                Does this help narrow down the issue at all?

                                  Dude just shrink it... And it sure isn't showing anything over 100 queries... And I tried clicking into - its too small..

                                  download.jpg

                                  If you click into that you can read it can you not..

                                    The pciture is a screenshot from wireshark - it was the max number of lines I could fit on my screen at one time. When I tried to cut and paste the text itself, the forum software rejects it as being spam, so it won't let me post it. However, I searched the capture file on my end - even though I was trying to resolve feedly.com, there were no entries for feedly.com in the capture (and other DNS requests are going out as expected at the exact same time). It's as if the request to resolve feedly.com is not even getting to the DNS resolver. I am not sure where along the way it is getting blocked.

                                      And strangest of all - the problem just seemed to fix itself without any intervention on my part. When I tried to browse to feedly.com, it resolved (unfortunately was not performing packet capture at the time). However, I notice that this is at exactly the same time that pfBlocker NG is updating itself/cron job. Is that just a coincidence, or is that pointing to an issue with pfBlocker NG?

                                        Spoke too soon - feedly.com resolved in firefox (still using the firefox internal cloudfare DNS lookup) but not safari at the same time - i.e. it could resolve when 1.1.1.1 was used but not unbound. As soon as pfBlocker NG finished its update, firefox could not resolve feedly.com any longer.

                                          Tried another packet capture while browsing to feedly.com, pinging feedly.com, and performing an nslookup via the command prompt. During all of that, feedly.com never appeared in the UDP port 53 packet capture, even though other domains did appear as expected (and resolved without issue) - including websites that I have never accessed in the past. The problem does seem to be limited to feedly. I remain mystified.

                                            Dude that restarts unbound! And yes that will cause you problems with resolving. As to not seeing anything for feedly in your sniff - because once its cached you don't have to go lookup it up again..

                                            How freaking often do you have pfblocker updating?

                                            Why don't you turn off that firefox nonsense?
