What libcurl version on what platform with what SSL library and version?

What does VERBOSE (or even better the DEBUGFUNCTION) display? How come not
using 990 in the URL doesn't work when it defaults to 990 for ftps:// urls?

Neither? You mean you try explicit on that same port as well? Implicit and
explicit can't work on the same port number.

Can you try for example the openssl tool and connect to this server? (assuming
you use libcurl built with OpenSSL...)
