      Folks,
      Last night I had to reboot my ISP (at&t) router and got new IPs - first time in an year+.
      My DNS provider is google domains and all my dynamic IPs are (were) with the old IP. When forcing renew got the error in subject on my log.
      Rebooting, deleting the entries from the service didn't help. The new ones created now have a 0.0.0.0 IP.
      Installed ddclient on ubuntu and worked fine.
      Any help to troubleshooting this issue is appreciated.

      This happened from two different locations by the way, specs below:

      First:

        Hi,
        first of all you should edit your post and remove/mask serial and device ID.
        Second: did your ever check if your dyndns command for renewing the IPs is working?
        Is it exactly the same command when using your Linux host?

        Regards

          Ok, thanks, done.

          From pf I only can see the entry in the log that I have in my subject.

          That was configured over an year ago and worked. Now that the IP changed, it is not working. Even deleted and recreated the entries in pf to no avail.

            You should see your setting in services - ddns menu (not sure about the exact wording)!?

            At least at my pfSense I can see and edit the command for updating the ddns service.

            Regards

              Yes, correct. It is there and with IPs 0.0.0.0 (the new one created for test) and N/A the old one (already in my config for years). In fact I've moved the install to another location in Jan and it did update the IPs. Either pf 2.6 or google are at fault.

                    That patch is in the 'recommended patches' list in the new System Patches package so it's one click to apply it.

                      @stephenw10 I was very pleasantly surprised this morning when I updated package patches and saw the list of recommended patches with Redmine numbers listed. This is great!

                        Hi, I have the same problem. The response from namecheap is not correctly parsed. I applied the patch for Redmine #12816 to pfSense 2.6.0-RELEASE, but the response is still not parsed. The cached IP still says 0.0.0.0. I have also rebooted the router.

                          What is namecheap responding with?

                          Does it correctly update from a different dyndns client?

                              I removed the .cache file generated for namecheap, and now when I save the settings for its client, the .cache file contains "0.0.0.0|1661343037", and in the UI it's displayed "0.0.0.0".
                              I also added a freeDNS API Version 2 client, which corectly registers and caches the dynamic IP.

                                Hmm, looks OK. Are you actually seeing the 'Unknown Response' error logged?

                                    Hmm, looks exactly like what that patch should correct.

                                    Does it show as applied? Is the change actually present in /etc/inc/dyndns.class?

                                      This is the namecheap section in the /etc/inc/dyndns.class file:

                                            With my limited php experience I was able to find out the problem.
                                            The response is an xml sent on one line, with the encoding set to utf-16, so line $ncresponse = xml2array(substr($tmp, strpos($tmp, "\n") + 1)); gets executed, and $ncresponse is actually empty.
                                            Which means that $ncresponse does not match any of the ifs. so it ends up in the last else.
