Unable to get output when sending commands via ssh.net to aruba switch or virtual controller

Question

I am attempting to remote into a virtual controller to run aruba commands into the console such as "show run" etc but no output is coming up for the commands. It appears I am able to successfully connect, and I am not seeing any errors, but nothing happens when running a command.

I have connected via putty to validate the commands, and also validate credentials. I have been able to do similar functionality via python, but am needing to be able to do this via C# for dependency reasons.

                var methods = new List<AuthenticationMethod>();
                methods.Add(new PasswordAuthenticationMethod(UserName, Password));
                var con = new ConnectionInfo(virtualController, 22, UserName, methods.ToArray());

                Console.WriteLine("Attempting Connection with Network...");
                var Client = new SshClient(con);
                Client.Connect();
                Console.WriteLine("Successfully Connected.");

                var cmdRun = Client.RunCommand(showClients);
                var result = cmdRun.Result;
                Console.WriteLine(result);

                cmdRun = Client.RunCommand(showRun);
                result = cmdRun.Result;
                Console.WriteLine(result);

                Client.Disconnect();

The console outputs "Successfully Connected." and continues to execute all code, but never outputs anything on the line:

Console.WriteLine(result);

I would expect for the terminals output that I would see when running this command via putty.

I use SSHClient instead of Client . Using my class from this answer , here's some sample code after calling Client.Connect() :

SSHStream = SSHClient.CreateExtShellStream("dumb", 120, 80, 0, 0, 65536);
if (SSHStream != null) {
    DoCommand("no page");
    Connected = true;
}

var result = DoCommand("show cdp neighbors | begin Port", TimeSpan.FromSeconds(2), "#");

Here is the helper method:

public static IEnumerable<string> DoCommand(string c, TimeSpan? timeout = null, string prompt = "#") {
    return SSHStream.DoCommand(c, timeout ?? TimeSpan.FromSeconds(2), prompt);
}
