Aruba SDN and Network Optimizer?

[Cajuntank MS]

On a new install of a SDN controller, Optimizer, and associated Microsoft SDN APIs, I am having a problem with the SDN controller and the Microsoft SDN Managers communicating over https. According to my log files, the Microsoft SDN Listeners on the Front Ends of my Skype for Business servers are communicating great with the Managers on some other servers. The communication from the Managers to the subscriber (the Aruba SDN controller), and according Manager logs, I see the continued output example of (domain name was changed to protect the innocent...lol)

I am following https://msdn.microsoft.com/en-us/library/office/dn785201.aspx in regards of correct certificate needs for the Managers (the Aruba SDN Admin Guide documentation was followed for certificate request and install from my internal Windows CA for the controller and am using the same CA for cert requests and signing for the Managers).

Just wondering if anyone has any further insight or experience they could share?

Hi Cajuntank,

I consulted with a colleague and it appears that you might need to enable TLS v1.2 on the lync server. I've attached some documentation that may help (I had to break it into 3 screenshots). Please let us know if anything else is needed:
