It's hard to say what the problem is, since I don't have your site to play with. The authorization_basic part of the upload script, is the integrated login put out by the server, it's not for a separate login form/page.

It looks as if the url you are entering, is redirecting you to another site. Maybe the proxy server is sending the message, have you added the proxy handling? You didn't post the code you are using.

Lwp works in a very straight forward manner, when the upload site redirects, or something else devious, you may need to use WWW::Mechanize.

The first thing I would try, is to use the URL you show above, as the upload URL, if you are not already. You can also try adding 

$ua->requests_redirectable ( ['GET', 'HEAD', 'POST'] )
# or
push @{ $ua->requests_redirectable }, 'POST';

You may need WWW::Mechanize
