That's very strange. CURLE_COULDNT_CONNECT means that the TCP connect fails,
so if you can telnet to the same IP and port number something is truly wrong.

Can you wireshark the connection and see what exactly happens over the
network? Alternatively, use strace or similar to see what exact system calls
libcurl uses that end up failing.
