I think your problem is that, like many others, your proxy server don't
support FTPS. Proxy servers that don't support FTPS don't know how to
decode the SSL encrypted communication that needs to exist between the
client and the server.

See here for a list of compatible clients, servers and proxy servers:
http://www.ford-hutchinson.com/~fh-1-pfh/ftps-ext.html

However, looking at the specs for your proxy, it looks like it does
support SOCKS, which I think Curl supports as well. Maybe try using the
SOCKS proxy settings for your communications.
