Comment 44 for bug 1006776

Ok, I'm pretty sure I've found the issue here and it's nothing to do with either Java or even NSS.

I can access the URL fine on both machines with wget and curl. The same issue I patched earlier has also been fixed in OpenSSL (used by your ruby client) recently:

* Thu Oct 31 2013 Tomáš Mráz <email address hidden> 1.0.1e-16
- do not advertise ECC curves we do not support
- fix CPU identification on Cyrix CPUs

My box:

Name : openssl Relocations: (not relocatable)
Version : 1.0.1e Vendor: Red Hat, Inc.
Release : 16.el6_5 Build Date: Mon 04 Nov 2013 16:10:09 GMT

After a yum upgrade of openssl, surprise, surprise...
