No message or timeout while trying to connect to sftp server

I am trying to connect to the sftp server and I am not getting any exception or timeout, only increasing memory usage.

I am using the EnterpriseDT.Net.Ftp library

My code looks like this:

XmlConfigurator.Configure();
      Module1.Logger = LogManager.GetLogger("SftpTester");
      try
      {
        Module1.Logger.Info((object) "[EnterpriseDT] - Start");
        Uri uri1 = new Uri("ftp://*****");
        // ISSUE: explicit reference operation
        // ISSUE: variable of a reference type
        Uri& uri2 = @uri1;
        int port = ****;
        string str1 = "******";
        // ISSUE: explicit reference operation
        // ISSUE: variable of a reference type
        string& UserName = @str1;
        string str2 = "*******";
        // ISSUE: explicit reference operation
        // ISSUE: variable of a reference type
        string& Password = @str2;
        SecureFTPConnection secureFtpConnection = Module1.InitConnection(uri2, port, UserName, Password);
        Module1.Logger.Info((object) "Connecting to ftp...");
        secureFtpConnection.Connect();
        Module1.Logger.Info((object) "Connection Successful!!!");
        try
        {
          Module1.Logger.Info((object) "Disposing connection...");
          secureFtpConnection.Dispose();
        }
        catch (Exception ex)
        {
          ProjectData.SetProjectError(ex);
          ProjectData.ClearProjectError();
        }
        Module1.Logger.Info((object) "Connection Disposed.");
      }
      catch (Exception ex)
      {
        ProjectData.SetProjectError(ex);
        Exception exception = ex;
        Module1.Logger.Error((object) ("Main() - " + exception.Message));
        Module1.Logger.Error((object) ("StackTrace: " + exception.StackTrace));
        if (exception.InnerException != null)
          Module1.Logger.Error((object) ("InnerException: " + exception.InnerException.Message));
        ProjectData.ClearProjectError();
      }
      finally
      {
        Module1.Logger.Info((object) "[EnterpriseDT] - End");
      }

  private static SecureFTPConnection InitConnection(ref Uri uri, int port, ref string UserName = "", ref string Password = "")
    {
      Module1.Logger.Info((object) "InitConnection() - Setting Up Connection");
      SecureFTPConnection secureFtpConnection = new SecureFTPConnection();
      secureFtpConnection.LicenseOwner = "*******";
      secureFtpConnection.LicenseKey = "***********";
      secureFtpConnection.ServerAddress = uri.Host;
      Module1.Logger.Info((object) ("\tHost: " + uri.Host));
      secureFtpConnection.UserName = UserName;
      Module1.Logger.Info((object) ("\tUsername: " + UserName));
      secureFtpConnection.Protocol = FileTransferProtocol.SFTP;
      Module1.Logger.Info((object) ("\tProtocol: " + FileTransferProtocol.SFTP.ToString()));
      secureFtpConnection.ServerValidation = SecureFTPServerValidationType.None;
      Module1.Logger.Info((object) ("\tServerValidation: " + SecureFTPServerValidationType.None.ToString()));
      secureFtpConnection.AuthenticationMethod = AuthenticationType.Password;
      Module1.Logger.Info((object) ("\tAuthenticationMethod: " + AuthenticationType.Password.ToString()));
      if (port > 0)
      {
        secureFtpConnection.ServerPort = port;
        Module1.Logger.Info((object) ("\tServerPort: " + port.ToString()));
      }
      secureFtpConnection.Password = Password;
      Module1.Logger.Info((object) ("\tPassword: " + Password));
      return secureFtpConnection;
    }

Any idea if this is a timeout error or am I blacklisted?
