Hi,

Check that your HTTP proxy allows SSL, that you have set the httpProxy
directive correctly (  httpProxy=server.name.blah:3128   for example ).
If your HTTP proxy requires authentication make sure the httpUser and
httpPassword dirctives are set too. The configuration should be the same
as your older RHEL systems BTW.

Also, there may be a problem with the initial release of yum-rhn plugin,
try using pup to update ( graphical ) first.

Cheers
