Trying to connect to a secure FTP server and it worked fine in FileZilla, but when I used the same credential in a batch download program, it failed and show me this in the log:

Below is my code
=================
// Instantiate SecureFTPConnection
SecureFTPConnection ftpConnection = new SecureFTPConnection();
SecureFTPConnection.LogLevel = LogLevel.All;
// set the license
ftpConnection.LicenseOwner = "DFDFDFD";
ftpConnection.LicenseKey = "XXX-XXXX-XXXX-XXXX";
// setting server address and credentials
ftpConnection.ServerAddress = serverAddress;
if (serverPort.Length != 0)
{
ftpConnection.ServerPort = Convert.ToInt32(serverPort);
}
ftpConnection.UserName = userName;
ftpConnection.Password = password;
ftpConnection.ServerValidation = SecureFTPServerValidationType.None;
// connect to the server
// By default, auto-login is on so Login doesn't need to be called
myLog.logtext("Connecting to server " + serverAddress);
ftpConnection.Connect();
myLog.logtext("Server connected!!");
ftpConnection.ChangeWorkingDirectory(initialDir);
