HCIBench version is 2.8.3.
vSphere\vSAN version is 8.0.3
When attempting to run a Test the process fails almost immediately with "[ERROR] Unknown Failed...".
Deploy.log shows - {"vSAN-Datastore"=>["host1", "host2"]} Unable to connect ESXi host
On the ESXi hosts side logs show "SSH session was closed for 'root@HCIBench_IPAddress' fraction of a second after opening the session; as though the SSH login is rejected.
SSH and Shell services are enabled and running on the hosts. No Firewall restrictions. I am able to SSH with the same credentials form the HCIBench machine's command line to these hosts.
What could this be? This is a two-node vSAN cluster.
A few weeks ago this used to work. The only changes that took place since the last time it worked: a) replaced storage controllers on these two hosts and b) replaced vCenter machine self-signed SSL certificate with a custom one.
