[OPNsense 24.7.9_1-amd64] High Availability Sync not working [SOLVED]

[niei]

Hi everyone,

I am having a problem with my HA Setup between two Sophos XG210 running OPNSense 24.7.9_1-amd64.
The CARP failover and configuration works great. However the Config/State Sync between the two firewall doesn't seem to work. When I try to "Perform synchronization" in System -> High Availability -> Settings, the page loads for about ~75 seconds and then displays the message "The backup firewall is not accessible or not configured.
" even though i can see traffic being allowed on the second firewall and the configuration (ip addresses and password) being correct.

Anyone experiencing the same strangeness?

See attached fw02-logs.png, fw01-config.png and fw02-config.png and fw02-rules.png

What are the listen interfaces for the web UI set to?

Hi Patrick

Thank you very much for your Help!
That solved it! i added HA to the listen Interfaces. =)

I wonder how it worked before, when i initially set up the synchronization.

Anyways, have a nice rest of the weekend.

There is a reason for the word "recommended" in the default setting "All (recommended)".
