      I make a new try.

      Reinstall both pfsense on 2.4

      Configure Interface
      Configure Sync
      Configure firewall => perfectly sync on slave
      configure DNS forwarder => perfectly sync on slave
      Configure DHCP  => perfectly sync on slave
      Configure Virtual IP => perfectly sync on slave

      etc
      everything work and everything is perfectly sync on slave

      I make a backup of Pfsense Master and I Load this backup on Pfsense Master to check if it's work, everything is here, but syn is broken :

      A communications error occurred while attempting to call XMLRPC method host_firmware_version: @ 2017-11-03 16:58:33

      Somoene have an idea ?

        What is in the system log? There should be an explicit version check line like this:

        Nov 3 18:49:01 php-fpm 536 /rc.filter_synchronize: Beginning XMLRPC sync data to https://172.25.254.2:443/xmlrpc.php.
        Nov 3 18:49:01 php-fpm 536 /rc.filter_synchronize: XMLRPC reload data success with https://172.25.254.2:443/xmlrpc.php (pfsense.host_firmware_version).
        Nov 3 18:49:01 php-fpm 536 /rc.filter_synchronize: XMLRPC versioncheck: 17.3 – 17.3

            Sounds like your SYNC interface is not configured correctly. Can you ping across it? Check the firewall rules on it.

                Are you passing the traffic on the sync interface on the secondary?

                Are both nodes set to the same webgui settings (http/https/port) and have the same username and password set?

                  Sorry fo the response delay,

                  Yes both node are on https same port.

                  Both node use dedicated ionterface for the sync, no vlan .

                  Here are the new log :

                  Master and slave can ping each other.

                  Each time i make a change on master it's very long to validate .

                  Thanks for your help Derelict.

                    Can you bring up the webgui on the secondary at the time?

                    Do firewall rules pass xmlrpc (webgui) traffic on the sync interface?

                    If looks like the primary cannot connect to the secondary there. Need to isolate the reason why that is so.

                            Hallo,

                            I used the HA1 IP 192.168.200.1 and HA2 IP 192.168.200.2. Normally netmask /24 for the network 192.160.200.0/24.
                            But after double checking, on the slave, the netmask was /32. I don't know how it was here?
                            After correction, all is now working fine.

                            Rgds.

                              Hello,
                              Thanks for tip, I had this correctly configured, but I find out fact, that my sync is not working, when I have my DNS resolver Turned ON. May be this will also help somebody.

                                I wanted to simply add that I had this same problem and thankfully found your suggestion to turn off DNS Resolver....this is unfortunate that it is required for HA Sync to work. I'll continue to investigate.

                                My error log also stated "The pfSense software configuration version of the other member could not be determined. Skipping synchronization to avoid causing a problem!"

                                    @vigorfac said in High Avail. Sync broken:

                                    Nov 7 12:40:18 php-fpm 51646 /status_logs_settings.php: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1', the output was '[1510054818] unbound[90624:0] error: bind: address already in use [1510054818] unbound[90624:0] fatal error: could not open ports'

                                    The above error sounds similar to this bug in pfSense, which was since resolved:
                                    https://redmine.pfsense.org/issues/7326#note-2 (the code didn't wait long enough for unbound to stop before trying to start it again...in our case the master server was unaffected but the backup router would end up with unbound not running)

                                    re: HA sync, we have "DNS Forwarder and DNS Resolver configurations" checked in our setup and have no sync issues. So I don't think that by itself is an issue.

                                    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 reboot, or more depending on packages, and device or disk speed.
