Hi Due to some network issue from ESXi hosts cant ping the gateway due to this i think the hosts get disconnected after some time in cluster and gives the following error:
vsphere ha agent on this host could not reach isolation address gateway
Can you please confirm is the above error due to gateway issue....I have also tried to change the hostisolation address for a testing purpose i give another ESXi server IP in hostisolation. Disabled and re-enabled HA again but even now servers get disconnected from vCenter and goes into not responding state. PFA image for host isolation settings.
