sftp is not ftps. ftp over ssl is what we call ftps. FTP-like tranfers over
SSH is what we call sftp.

You should tell us:

  - the exact error that happens, what libcurl says, what it returns etc

  - libcurl version and operating system in use

  - whether you really want implicit SSL as that's what you get with the
    FTPS:// in the url, while the standard prefers the ftp:// approach with
    CURLOPT_FTP_SSL set to the desired alternative.

For sftp, you should use sftp:// with a libcurl that supports it.
