Jeff, 503 is ServiceUnavailable:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

This means http://www.w3.org/TR/html4/strict.dtd
returns 503 - Not Jazz.

Unless there is a firewall on the server machine that prevents connection
from the server to http://www.w3.org/TR/html4/strict.dtd ?

Thanks Christophe, you posted so fast that I missed it!

I can successfully wget that url from command line, so no obvious physical barrier/firewall. Are there any other diags I can do to prove that my Jazz process is able to reach the internet?

The error is only reported through the client UI/log - I find no error on the server. Should I be looking somewhere other than <jazzinstalldir>/server/logs and <jazzinstalldir>/server/tomcat/logs/catalina.log?

Found it! Reasonably cool User Error, with some misdirection from the error messages. The key is in the URL used in configuring the repo connection...

URL to use for browsers - https://<servername>:<port>/jazz/web
URL to use for clients - https://<servername>:<port>/jazz

If you happen to make the mistake of pasting the browser URL (.../web) into a repository config field in the RTC client, you wind up with the mystifying 503 errors.

I'm inclined to think that there may be something worth fixing in that flow - don't really want my server generating unintended outbound web requests (if that's really what happens in this case), and certainly could have benefited from a more relevant error message somewhere.
