Thank you for reminding me about this problem, which we seemed to have the same in some of our 1500D a-p HA clusters. I'm assuming it happens only on the slave unit in your case too. We don't use it so often so we left the problem undealt for long time. But I finally open a TT at TAC and yesterday we had a remote debug session.

The cause was the interface subnet was not on the routing table in HA management vdom vsys_hamgmt, which is not visible with regular command. The tech broke HA and re-built mgmt1 ha-management interface on both unit and recover it.

You can check if your case is the same as ours or not with below command at your managment vdom (if multi-vdom environment):

xxx-xxx (management) # diagnose ip router command show-vrf vsys_hamgmt show ip route
