Plugin updates fail after pointing to Jenkins update location

[Harpel, Craig]

I changed my Hudson 1.384 update center to point to http://updates.jenkins-ci.org/update-center.json.  When I try to update plugins, it fails with the following trace (example is for the backup plugin):

Do you still see it now? What if you hit that URL from your browser?

I just did wget to this URL and it works for me. Any chance it's caused
by your firewall?

Yes, there's a very good chance that the problem is the firewall or proxy. Let me check that out before you take this one seriously. Thanks.

[Harpel, Craig]

It doesn't work for me from a fresh Jenkins install either. It seems they've added a challenge step in the web proxy ("are you sure you want to go to this site?") if the URL isn't yet recognized by the proxy. If I go to that URL directly in firefox, I get the challenge, and I can download it. URLs are added automatically within 5 days, so hopefully this won't be a problem soon.

Sorry for the false alarm.
