Code Snippet -

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

            bool success;

            //  Any string unlocks the component for the 1st 30-days.
            success = ftp.UnlockComponent("Anything for 30-day trial");
            if (success != true)
            {
                Console.WriteLine(ftp.LastErrorText);
                return ftp.LastErrorText;
            }

            //  If this example does not work, try using passive mode
            //  by setting this to true.
            ftp.Passive = false;
            ftp.Hostname = parameters.HostName;
            ftp.Username = parameters.UserName;
            ftp.Password = parameters.Password;
            ftp.Port = 20017;

            //  We don't want AUTH SSL:
            ftp.AuthTls = true;

            //  We want Implicit SSL:
            ftp.Ssl = false;

            //  Connect and login to the FTP server.
            success = ftp.Connect();
            if (success != true)
            {

            else
            {
                //  LastErrorText contains information even when
                //  successful. This allows you to visually verify
                //  that the secure connection actually occurred.
                Console.WriteLine(ftp.LastErrorText);
                Console.WriteLine("FTPS Channel Established!");

                }
                else
                {
                    success = ftp.PutFile("C:\\Test\\test.txt", "test.txt");

                    if (success != true)
                    {
                        //ftp.Disconnect();
                        return  "---------Upload Error  --------- " + ftp.LastErrorText + "---" ;//Upload Error.
                    }
                    else

Did you try setting ftp.Passive to true? When set to false you are in active mode which often fails. In Active mode the FTP server will open a connection to your computer (an incoming connection) which often fails (firewalls). In Passive mode all connections are made by your program (outgoing connections to the FTP server). Firewalls normally won't object to that.
