You mean you invoke this from a web server? Then I would say that the most
likely reason for this failure is a difference in evironment.

A failure does not produce anything on stdout so of course those command lines
show nothing if they have the same error your original program has.

Run 'strace curl' instead and store its output to see what causes it to fail.
Or just use curl as you do but make very sure to store and show the text that
appears on stderr.
