This article discusses edges that de-activate suddenly after a HA failover.
-When the edge is in HA state after activation, the VCO communicates with the Active edge and if the standby edge is also properly activated, the active edge will send a HA_STANDBY_ACTIVATED event to the VCO which ensures that both active and standby are properly activated with the correct certificate.
-If the standby edge is not properly re-activated/activated while the active edge is activated, the edge will continue to function without any issues, but if a HA failover occurs, the VCO will notice that the standby box is using incorrect certificates/information, then the VCO will de-activate the edge automatically and this will need proper factory reset/activation.
-During that time, we can identify that this is the issue by checking the below logs:

2024-03-01T00:22:44.328 INFO [mgd (12200:Heartbeat:12708)] VCO requested edge to deactivate itself
----------------
This is an expected behavior of the edge, when the certificates do not match the VCO will trigger a de-activation request on the VCO after the failover and this is the expected behavior.
