  <p>Code:</p>
  
  <pre><code>public TelnetConnection(string Hostname, int Port)
          {
              tcpSocket = new TcpClient(Hostname, Port);
  
          }
  </code></pre>
  
  <p>I have searched here looking for this problem and it seems pretty common. Some people are saying the host truly is unreachable (this is not the case), its a Microsoft .NET problem or its just an exception that can be ignored. I can't seem to get the program to pass it though if it is something that can be ignored. I also can't seem to find any solutions as to fixing it. I'm pretty lost on this one, any help would be appreciated.</p>
