So as everyone has probably seen, vSphere 6.5 is now GA. One of the features i have been waiting for the most is vCenter HA. I have spent some time trying to get this working in my lab. Unfortunately after countless tries i was stuck. Thanks to folks in the vExpert Slack for helping me try to resolve this, but unfortunately this was a case for VMware Support. Every time I would try to configure vCenter HA using the Advanced Wizard, I would get the following error.
