Description

Configuration synchronization via XMLRPC is enabled. Configuration appears to be syncing, but failover of the frontend LAN IPs does not occur when the primary pfSense firewall goes offline. Secondary always shows an error pertaining to multiple frontends using the same undefined IP, and HAproxy does not function when the secondary is the active firewall. This causes a production outage.

Try testing on the 25.11-BETA if possible. I'm not able to reproduce it there which indicates it was likely fixed by related changes present in the 25.11 version.

Unfortunately I cannot run beta software as this is for a production environment. It seems it'll be in my company's best interest to move to HAproxy on a standalone pair of systems for future stability, so will be taking that route.

Hello,

25.11 is now in stable. Let us know if you can still reproduce this issue on the latest stable build.
