New Post: Server String is null or empty

I have an SSIS (SQL Server Integration Services) package that is c# based. I am trying to connect to a MySQL server using the SSH Renci library. Here is what I am trying:

using Renci.SshNet.Common;
using Renci.SshNet;

SshClient client;

client = new SshClient("123.45.3.45", 3306, "MyName", "MyPassword");
client.Connect();

I get an error: Server string is null or empty. Below is the full message.

I have three hairs left on my head and would like to salvage the remaining strands. Any help is greatly appreciated!

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Server string is null or empty.
