Check in /etc/sysconfig/rhn/up2date and make sure the values are sane for your environment. Pay special attention to 'serverURL' and the Proxy settings. – Scott Pack Mar 6 '11 at 1:21
@packs, should that not be an answer rather than a comment? – Wesley Mar 6 '11 at 4:51

@Packs You confuzzled me with a lack of a question mark. Ninja! – Wesley Mar 7 '11 at 3:32

The error is exactly what it says: it can't connect to the RHN server. If you paste the contents of /etc/sysconfig/rhn/up2date (as @packs suggested in his comment), you can use the URL to verify whether or not its up. For example, if you were using a mirror, that mirror is--perchance--shutdown.

Also verify that your server has internet connectivity, and try running a traceroute to the server (and other URLs) to make sure its not a local problem.
