It may not be related, but in the past I have needed to rebuild libNSS and Curl in CentOS 6 due to an upstream patch the explicitly disabled TLSv1.2 in the default list of supported versions. As I recall, this was done to maintain support for servers that could not work when the negotiation of SSL/TLS was longer than X bytes. Unfortunately, I can't find the bug I referenced at the time. If it's like Curl, you might be able to explicitly enable TLSv1.2 on the command line, else I suspect you could recompile the source RPM, removing patches if required.
