System.Exception: KeyExchange Failed while setting up with IIS

[#1]

I have installed QlikView server and IIS web on separate machines. I have also added my IIS web into management console and I am able to see all the settings.

However, when I open access point it shows "No Server" error. Upon checking logs I found that there is some exception raised by QlikView as shown below. Can anyone help with this?
