Trying to use the New-NcCluster cmdlet to start the cluster setup process. The node IP is configured using node setup and the admin password is set.
The next step is to connect to the node IP using Connect-NcController but the connection fails.
Connect-NcController 192.168.137.201 -Credential $cred
Connect-NcController : Could not connect to 192.168.137.201 on port 80 for protocol HTTP.

This shows the connection tried HTTPS then down to HTTP.
Here's an attempt forcing HTTPS
Connect-NcController 192.168.137.201 -Credential $cred -HTTPS
Connect-NcController : database cluster_id_rdb is not open

Without a connection the New-NcCluster is useless (obviously).
Also, the web browser interface to run cluster setup doesn't work either - just get a blank page.
This has been attempted on a FAS2552 running 9.6P4 as well as the latest simulator.
Tried PSTK 9.6 and new 9.7.
BTW - this DID work in older versions - but it's been a while since I've tried it so couldn't say WHEN it broke 
Any ideas?
