You're using the -U option which specifies a proxy user/password, not
a web site user/password. Are you running through a proxy? If not (or even
if you are), then you need -u to use HTTP authentication (and --anyauth
to let curl automatically choose the best HTTP authentication method).
Note also that a 404 error is not an authentication error code.

curl supports HTTP authentication directly, but many web sites implement
their own authentication methods which use cookies instead. So, even with
-u, it still might not work. If that happens, then trace a successful web
browser upload (using LiveHttpHeaders for Firefox, or similar features on
other browsers) and compare that to the output you get when you add the
-v option to curl.
