XMLRPC sync operation timed out

[noel.alanguilan]

Hello folks,

I am setting up an XMLRPC sync according to the online book: https://docs.netgate.com/pfsense/en/latest/book/highavailability/example-redundant-configuration.html

The 172.16.X.X were followed and the firewall rules for the sync interface was added to both firewalls

The sync is happening between an XG-7100 as the primary (172.16.1.2) and an SG-8660 as the secondary (172.16.1.3). The two units are directly connected to each other via a crossover cable. On the XG-7100: eth8 with a VLAN tag and members 8, 9t, 10t and on the SG-8860, OPT4.

I have been getting the following error messages:

Apr 24 13:18:11 php-fpm 390 /rc.filter_synchronize: The pfSense software configuration version of the other member could not be determined. Skipping synchronization to avoid causing a problem!

I am not sure what I did wrong. Can anyone help check it?

As an addendum, both firewalls are running pfsense 2.4.4 Release p2

Hardware in an HA pair must match.

Hello. Just a clarification. When you wrote "HA pair must match" do you mean they have to be two units have to be the same model?

Thank you.

Yes. Particularly the interfaces.
