Your proxy should should accept SUSE domain (or at least selected sites used like updates.suse.com and scc.suse.com) without authentication.

You need to populate proxy setting in YAST and to add two lines with your proxy information to /etc/profile, for example:
    export http_proxy=""
    export https_proxy=""
Also add above to /root/.curlrc

You might need to do some packet captures with say tcpdump or wireshart to see what it's doing (and not doing...).
