Error when uploading file to MOS

When I tried to upload a file via curl to MOS I get the following:

root@server:/var/explorer/output# curl -T explorer.004a9928.server-2016.05.16.14.51.tar.gz -u "user@mail.mil" "ftps://transport.oracle.com/issue/3-xxxxxxxxxx/"

Enter host password for user 'user@mail.mil':

Is there another port I need to try and how do I set it up with curl?

Thanks
