Qlikview SSL Integration not working

[asnls]

I followed few documentation and configured SSL and was able to access SSL url  dashboards.

When we tried to integrate that with the other application portal, it is failing and i am seeing an error like 

[SocketException (0x2746): An existing connection was forcibly closed by the remote host]
   System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) +97
