31016 <= Any clear Reason ?!

[el5ateer]

I want to know a more clear reason for the error 31016 using FTP Plugins .. I use this code

------------------------------[[ SCRIPT: Page: Page1, Object: Button2, Event: On Click Script ]]------------------------------
-- Get the path of the image from the Input Object --
path = Input.GetText("Input1");

-- Separate Image Name from the rest of the Path --
psep = String.SplitPath(path);
-- Specify File name + Extension --
file= ""..psep.Filename..""..psep.Extension.."";
-- Connect to the FTP Server --
FTP.Connect("*******.*******.*******", "*******", "*******", "", true);
-- Navigate to the Folder of Upload --
FTP.ChangeDir("/****");
-- Check Whether a file with the same name and extension there --
exist = FTP.GetFileInfo(file);
-- If a file with the same name was found .. Error Message , Else, Upload --
if exist == nil then 
	FTP.Upload(path, file);
 	Dialog.Message("Image Uploaded Successfully", "Done, Image was uploaded .. Congrats.", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);end
if exist ~= nil then Dialog.Message("Sorry", "File already exists .. Please rename the fgile and try to upload it again.", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);end

FTP.Disconnect();

I get this error after "most of" FTP actions their .. I guess it has something to do with the FireWall or whatever .. but i want, please, a clear point of view (detailed if possible)

thnx and sorry for disturbance

Yours,

ya i read it in the Help File but .. What is meant by it ??! It's not clear or known for me when it comes to "Request to set data port rejected (PORT command failed). "
and is it something wrong with the code or with the connection or .. ?!

Some things to try:

• Try connecting in passive mode. (If your server supports it, it's less likely to get blocked by your firewall.) Use FTP.SetPassiveMode(true) to turn it on.
• If your server wants to use a specific data port, make sure you're using the correct one. Use FTP.SetDataPort() to set it if you need to.
• If your server doesn't support passive mode, you'll need to open that data port in your firewall.
• Try disabling your firewall to see if that makes any difference.
• Search on google.com to learn more about FTP and the ports involved.

Sorry, I got busy and forgot to get back to this thread.

Looks like you have some avenues now though to persue.
