ViPR 2.3 Add Storage Provider, Add Storage System not working VNXe

Who can I talk to about the ViPR side of connecting to a Storage SMI-S Provider?

I have already consulted with some Eng resources on the vVNX (VNXe) team and they indicated that the provider for this is running on the Unisphere interface, on port 5989, username is: local/admin  ..password is configured Unisphere password.

However I have tried all combinations of adding via 'Add Storage Provider' and 'Add Storage System', along with trying different port numbers (like 5988, and 443, etc) and cannot get ViPR to discover.

The closest I can get is if I add VNXe in 'Add Storage System' with port 5989 and user: admin and Unisphere password then it says registered (check), but Status shows 'thinking' (refresh icon), but thinks forever.. (or sometimes comes back with 'broken pipe' error)..

The only other way that shows something curious is if I use 'Add Storage Provider' and add it as 'Third-party Block' then use the username 'service' and configured service password, then it comes back as green check but I don't think anything works.. I think it just checks that it successfully connects to an SSH server (that option uses port 22)..

On the storage side if I go to https:// :5989/ECOMDebug   ..the page works so I believe the SMI-S Provider is listening.

I would like to find a suitable resource to discuss the operation of this from a ViPR-side perspective as I am not able to find much documentation on connecting to VNXe / vVNX..

Any help is appreciated.

UPDATE:

This is the error I see when I attempt to add the storage appliance in what should be the proper way:
