      Hi,

      I'm using latest 2.4 (2017/10/04) and after updating to this version two of my custom dyndns Provider (ddnss.org, dynv6.net) recognitze my new adresse but no-ip and selfhost failed. In past versions all of them failed after a reconnect so I wasn't able to do something from remote.

      The difference I see is that curl try to reach the provider but could not resolve the adresses

      unbound (resolver) is doing a lot of things at startup like dnssec and pfblocker, maybe should /rc.dyndns.update wait until unbound is ready or /rc.dyndns.update should restart after unbound is ready.

        i do have exactly the same behaviour. some of my dyn DNS work properly, some like freehost don't update automatically.
        It seems that the "first" of my dns providers does not sync on WAN IP change.

          As you already figured out, this isn't a "Dynamic DNS" problem, but DNS - on pfSense - problem :
          @pfadmin:

          Oct  4 09:04:47 pfSense php-fpm[50529]: /rc.dyndns.update: Curl error occurred: Could not resolve host: dynupdate.no-ip.com
Oct  4 09:05:17 pfSense php-fpm[50529]: /rc.dyndns.update: Curl error occurred: Could not resolve host: carol.selfhost.de

          Maybe unbound isn't ready to resolve yet, after an IP-WAN switch, many process get restarted (and some several times).

          "Waiting for unbound to be ready" seems hard to implement, but delaying "rc.dyndns.update" could do the job.

          Here : https://github.com/pfsense/pfsense/blob/c7500634345edafd633c71f9ec4e183cbbec4ccb/src/etc/inc/services.inc#L1917
          a
          sleep(5);
          ?

          Btw :

Oct  4 09:05:23 pfSense php-fpm[50529]: /rc.dyndns.update: phpDynDNS: (ERROR!) No Hostname Provided.

          I advice you to remove this part in the setup, or finish the setup.

            What i did:
            I overrode the dns entry of carol.selfhost.de in the unbound settings. Hope it'll help.
