HA broken since update to 26.1.9

[StephB]

I have a pair of OPNsense firewalls in simple HA setup, regulary upgraded since 23.x . I use the standard upgrade procedure : upgrade fw2 (the backup), Enter Persistent CARP Maintenance Mode on fw1 (the master), upgrade fw1, Leave Persistent CARP Maintenance Mode on fw1. I run a ping from LAN to internet to check that traffic is flowing during the upgrade process.

Upgrade from 25.7.x to 26.1.6 went OK as usual. During the upgrade from 26.1.6. to 26.1.9, the traffic stopped during the reboot of fw1. The status of CARP was showing OK : fw1 as CARP backup and fw2 as CARP master.

With the 2 firewalls on 26.1.9, fw1 as master and fw2 as backup, I disconnected WAN interface on fw1 : CARP failover succeeded as showed in the dashboard but no traffic to internet. Ping to the LAN VIP and WAN VIP was OK.

Any hints to resolve this issue ?

Problem solved :
reinstalled version 26.1.2
restored config backup
checked HA : OK
upgraded to 26.1.9
checked HA : OK

Don't know what went wrong when upgrading 26.1.2 -> 26.1.6 -> 26.1.9 !?

Sorry for the noise.

It looks like it might have been an isolated issue that you had.

Glad you could resolve it. I also run two OPNsense (2x DEC750) in community version in HA, and I update them frequently. I didn't have issues yet, I mostly do this to catch issues like these early as well.
