Error when connecting from secure .net code hosted on IIS to Cassandra cluster

[Asit KAUSHIK <as...@gmail.com>]

Hi All,

I am using cassandra 2.1.3 , we have an application written in .net for
that we are using DataStax .Net Drivers . We are deploying this to our
production server (the .Net application) , we have created a static route
from our .net Webserver to the cassandra Cluster on port 9042 .
The Webserver is on a secured network.
But still i am getting this issue . On my local environment it is
connecting to the cassandra cluster. Please point me to any solution on
this.

Below are the logs i am getting on the Cassandra cluster
