Getting Error when transferring file through FTPS (with TLS) though Connection to the server is being established.

I am not able to transfer text file over FTPS (with TLS). I am able to establish connection with FTPS server. Able to change the directory, but whenever i am trying to upload the file i am getting below log error. I have given both code details as well as error log details. please help.

Below is my code snippet for transferring file through FTPS server.

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 = true;
            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)
            {
                Console.WriteLine(ftp.LastErrorText);
                ftp.Disconnect();
                return ftp.LastErrorText;
            }
            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!");

                success = ftp.ChangeRemoteDir("/");
                if (success != true)
                {
                    return ftp.LastErrorText;//Directory Change Error.

                }
                else
                {
                    //string localfilename = "\\hgsqlp14\\Transfer\\BI\\PWC-t\\test.txt";
                    //string remotefilename = "test.txt";

                    //byte[] dataBytes = ConvertToArray(fileStream);

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

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

                }
            }
