I have 2 ESX 6 servers in an isolated environment (no internet access or local DNS). I am trying to deploy the vCenter appliance 6.5 to manage them. All devices are on the same subnet. Deployment appears to make through Stage 1 but Stage 2 errors with just an "Internal Error". I've tried adding my vcenter FQDN to both the local vcenter appliance and the machine I am running the set up from as I thought it might be DNS related, but no success. Any ideas?
Thanks
