Did you compare the request headers between curl and your application?

Your program doesn't set any size of the file you upload, making libcurl to
use "Transfer-Encoding: chunked" for it. Is that the reason?

The command line also uses User-Agent which your application doesn't seem to
use and your app sends proxy auth...
