Wolfspyre:
I've a pair of hosts running OPNsense 24.7.a_341 (X11SDV-4C-TP8F)

igb0 is their heartbeat interface, crossconnected

they can ping/interact across the hb interface.

failover still generally works... (carp)
however recently I noticed that an haproxy change I made didn't synchronize to the secondary....
I went to jiggle the handle, and got the response in the webUI `the backup firewall is not accessible or not configured`

this is weird, as things had been working fine (and honestly, I'm not sure when things **STOPPED** working, because the opnsense-log output is so clogged with the erroneous
`telemetry token missing in /usr/local/etc/suricata/rule-updater.config` messages, I didn't notice:

--- End code ---

however, I'm not really sure how to begin diagnosing this... backup of the primary config, and restore to to the primary host works, which presumably conveys that the config is okay.

running the /usr/local/etc/rc.filter_synchronize command manually on the primary

makes it hard to know if the deprecation warnings are contributing to the problem or not.

Suggestions?

Wolfspyre:
Huh..
I was really kinda hoping that someone here would be able to help...
Or at least to point me in a direction...

am I the only one encountering issues like this?

is this a known issue that I somehow just failed to read up on?

am I jus doin-it-wrong?

Would love a nudge in the right direction if someone has some pointers.

Patrick M. Hausen:
Try running supported release like 24.1.6 instead of a development version.
Check the firewall rules on the HA sync interface on the secondary node.
Use tcpdump to perform a packet trace on the HA sync interface.
The primary node must be able to login to the UI over the HA interface - did you change the interfaces setting for the UI?

Wolfspyre:
hai Patrick!
yea.
No changes to the firewall rules have occurred. hence the confusion. the sync between primary/secondary has been working fine for years.

carp is still working
ssh between the two works properly.
creds haven't changed

dev version has **USUALLY** been pretty stable.
that being said; switching the standby to from dev to 'production' got things back to synchronizing.

Thanks a bunch for the tip (altho 24.1.5 is the latest my standby sees... rebooting now to see if that changes anything... )

where are you seeing 24.1.6?

Patrick M. Hausen:
On all of my firewalls? Released last Thursday.
