Just updated vCenter 6.5 to version 6.5.0.30000 and HA has crashed out (see image).
Tried disabling/re-enabling with no luck
Maybe a bug in the new version?
Upgrading each ESXi host to "VMware ESXi, 6.5.0, 13932383", and rebooting each one, then enabling HA again fixed my issue.
I think it's a bug with the new VCSA Update 3, as it happened on both my vCenter installations.
Anyway - fixed!
Hi
Did you try to disable HA and then enable it on your cluster again?
As per my original post, yes I have.
Upgrading each ESXi host to "VMware ESXi, 6.5.0, 13932383", and rebooting each one, then enabling HA again fixed my issue.
I think it's a bug with the new VCSA Update 3, as it happened on both my vCenter installations.

In situations like this one, it's recommended to Re-Configure vSphere HA on your cluster (include disable HA Agents of all hosts and enable them again) although it must be done after updating all of your hosts successfully to an equal version (check build number of all host with Summary tab or running "esxcli system version get".
