vSphere HA agent for this host has an error: The vSphere HA agent is not reachable from vCenter Serv

[vjrk83]

Hello, 

All the hosts in cluster is failed and says the vSphere HA host status error in red.  I tried the following options to fix, but nothing worked out. 

Disabled and enabled vsphere HA at cluster level

Ran Reconfigure for vsphere HA at host level 

Disconnected and re-connected the host from the cluster. 

Also rebooted the host. 

Any other possible cause ? Anything to be done at the VCSA level ?

Hi,

I would start by looking at /var/log/fdm.log file  on the ESXi hosts (Fault Domain Manager log) and check if there are errors related to vSphere High Availability.

That may gives you some clues as well as the next steps to follow.

Regards
