Hey all.
I am currently still setting up my new nested ESXi lab.  I have ESXi 5.5 running as the underlying host(0) and then two ESXi 6 hosts nested on that. I have set up my DC, SQL, PSC and vCenter. All are booting up well.
I have managed to add my second host(2) to my cluster, however I am continuously having an error with adding the first host(1). This first host has been nothing but trouble. It had a couple of instances where it PSOD and when I attempt to add it, it will accept my root and pass and then after a minute ask me to accept the cert, then it will sit for 2 minutes and then present me with the attached error.
I destroyed the host(1) and rebuilt it. identical as the second host(2) (of course hostname, IP, etc are different) but I continue to get the same issue with adding it.  There wasn't much in a google search that helped.
The underlying host(0) has it's vSwitch set to promiscuous enabled. vCenter is sitting on host 2 (which are both connecting)
Any ideas?
Thank you.
