Description

HA setup configured. On one of the nodes, we see that heartbeat not found on interface 0/1.
On one of the nodes, when the command "show HA node" is executed, we see the following:
 
 Interfaces on which heartbeats are not seen : 0/1
On the other node, we see the following:
 Interfaces on which heartbeats are not seen : None

Resolution

Interface 0/1 on the secondary node is disabled.
Hence "Interfaces on which heartbeats are not seen : None" is observed.
Enabling this 0/1 interface on the secondary (or on the node where it is disabled) will resolve the issue.

Problem Cause

Critical Interface 0/1 on Secondary node was disabled which is causing HA heart beats to not transmit or receive.
