java.net.ConnectException: Connection refused: connect

Looks like I spoke too soon. deimos.apple.com resolves, but the app I use to log in as administrator is still not working. This is the error now:

ITunesU.invokeAction(): I/O Exception
java.net.ConnectException: Connection refused: connect

This code was working prior to Dec 13 and has not changed. Any suggestions on where I can start looking? (or maybe some way to find out more information on exactly what is failing?)

G4 400 PCI, Mac OS X (10.2.x), Single Proc, Third Party DVD

Port? Hm. I'm not seeing any special ports in the connection string.

I've got only a basic knowledge of Java, so I've been stumbling around producing debug output at various steps along the way. So far, it looks like things are bombming when the iTunesU.invokeAction(url, token) method is called. (Probably not a surprise.) I haven't traced in to that method, but I did dump the URL and TOKEN out.

URL
https://deimos.apple.com/WebObjects/Core.woa/Browse/---.edu

TOKEN (edited for obvious reasons)
credentials=Administrator%40urn%3Amace%3Aitunesu.com%3Asites%3A---.edu&identity= %22---------%28---%29%22%3C---------%40---.edu%3E%28Administrator%29%5B10%5D&tim e=1229655801&signature=---------(64 characters)----------

I submitted this around 7pm PST -- (made sure my server clock was in sync with a time provider while I was at it.)

Does that help?

It looks like you are still having a DNS problem.

Please run these commands in a terminal and post the output. You should be able to copy and paste a line and press return.

telnet deimos.apple.com 443
telnet 17.152.19.253 443

Please be sure to do this on the machine that is giving you the exception.

Ah... I think our network guys are restricting access by IP. (They block most multimedia content here.) I've got them checking into it now and will post again when I hear back.

Yep -- I was being blocked by a firewall rule. Thanks again for the help -- and the fast responses.

They don't want to open up iTunes access for everyone here because it violates corporate internet use policy. I've asked them if there is some way to use the DNS name for the rule, but somehow I doubt it can be configured that way.
