Never able to connect to (A/P) peer

[MeCJay12]

Hello! I have two VM series firewalls running on KVM. They were originally 10.2.8 but after a series of upgrade failures, they were wiped and reinstalled as 10.2.9-h9 using configs pushed from Panroama (11.2.2-h1 also upgraded from 10.2.8). For some reason, ever since reinstalling the firewalls, they will no longer connect to each other for HA. They use the Mgmt interface for HA1. I've confirmed they can ping and ssh to each other. when I run show high-availability state, they both say Connection down; Reason: Never able to connect to peer. Any ideas why this is happening?

Hi @MeCJay12 ,

If I remember correctly you can user Mgmg interface as HA1-backup, but you need to use dedicated interface for HA1.

Also it may sound stupid, but have you verified the HA1 peer addresses in both firewall configs? HA1 is Layer-3 and requires you to specific the HA1 peer IP. Is it possible that after redeployment the VMs got different IP addresses from the DHCP and HA configuration is no longer valid?

Thanks for the reply. You can use the Mgmt interface for HA1. I do not have an HA1-Backup config. This config is pushed from Panorama and was working pre-upgrade. The solution ended up being needing to re-import fresh HA keys from both peers to each other. I had downloaded the keys before upgrading just so I have everything before upgrading but I needed fresh HA keys.
