I'm deploying the VCSA on my ESXi 6.0 server and it's failed to start up and configure properly twice. I am seeing issues with the FQDN so I've switched to using the IP. Went back to my ESXi host to try and get it in the right domain so it can be accessible by FQDN but I haven't managed that either. I would like to get the ESXi host on the same domain as the Windows AD, correct the SSL Cert for that and repeat the process with the vCenter, but so far following several docs I haven't been able to pin it down. Currently I have both running in vshpere.local and using IP's of both and the install of the VCSA seems to have finally worked.
