FTP cannot go to the Windows server Public IP

I have a problem with FTP when I want to upload an image using a public IP, the Windows server can’t upload it, but if I upload it to hosting it works fine.
The situation is that my Windows Server Public IP can be called with an FTP user in WinSCP,

If anyone has succeeded, please help
