Needing assistance with DSE C# driver configuration over SSL

Question

Having trouble configuring a DSE C# driver to use SSL. I have spun up my own DSE Cluster with one node and node to node encryption as well as client to node encryption turned on. No errors! However below is a small code that I am using to test a that i can connect to the cluster with SSL.

class Program
    {
        static void Main(string[] args)
        {
            X509Certificate2Collection collection;
            using (var store = new X509Store(StoreLocation.LocalMachine))
            {
                store.Open(OpenFlags.ReadOnly);
                collection = store.Certificates;
            }

            var cluster = Cluster.Builder()
                .AddContactPoints("192.168.14.11")
                .WithCredentials("cassandra","cassandra")
                .WithSSL(new SSLOptions().SetCertificateCollection(collection))
                .Build();

            ISession session = cluster.Connect();

            global::System.Console.WriteLine("test");

        }
    }

I keep receiving the following error when it gets to the session:

"Dse.NoHostAvailableException: 'All hosts tried for query failed (tried 192.168.14.11:9042: AuthenticationException 'The remote certificate is invalid according to the validation procedure.')'"

I also imported both the nodes and cacert into my machines local.

On the cluster side it throws the following error: javax.net.ssl.SSLException: Received fatal alert: Cerrtificate_unknown.
