We are running vCenter VCSA 7.0u2b and tree ESXi 7.0u1c hosts in a HA-cluster in our VMware datacenter..
After a power-outage, one of our three ESXi hosts in the HA-cluster is red in the vCenter and we got the error "vSphere HA agent for this host has an error. vSphere HA agent cannot be installed or configured"
I have tried the following, but the error is still there:
I hope you can help me to solve this problem so we can get HA for that cluster up and running again.
Thanks in advance!
check /var/log/fdm.log on the host to see what is happening, it should give more detail. was there a change in certificate recently? Or any certificate issues, as that more than often is what causes this.
