we’re having an issue installing NGT from PC. The iso gets mounted but the installation doesn’t start, it sits there for a while then gives the error

NGT_INSTALLER_ERROR: Failed to establish secure connection with the UVM: 56

i have run the following

 $certificate = New-SelfSignedCertificate -DnsName $env:computername -CertStoreLocation cert:\LocalMachine\My

 winrm create winrm/config/Listener?Address=*+Transport=HTTPS "@{Hostname=`"$env:computername`";CertificateThumbprint=`"$($certificate.ThumbPrint)`"}"

 cmd /c 'winrm set winrm/config/service/auth @{Basic="true"}'

 netsh advfirewall firewall add rule name=\"WinRM-HTTPS\" dir=in localport=5986 protocol=TCP action=allow

which is a pain to have to do, sometimes it works but mainly it doesn’t.  i did think it might be to do with port 2074 and I need to check if thats open but as it has worked sometimes I think it must be.  The only joy I have is if I install NGT as part of a template and then follow the instructions. 

Enable NGT and mount the NGT installer on the cloned VMs by following the instructions in Step 12 of Installing NGT (choosing Skip and Mount).
NGT automatically identifies the ISO, update the configuration, and unmount the CD.

This works fine for new VM’s built from the template but it would be nice to be able to install bulk on old VM’s without having to mess around.

Also it looks like to do the install of NGT in the first instance it uses IP based to do the install is this correct?  But once installed (so in a template) it then uses IP-less from then on.  We are currently migrating from ESX running on Nutanix to straight AHV
