Hi guys, I've tried setting up CentOS 6.4, Nginx 1.4.1 with Google SPDY support and used spdycheck.org to check the site and all SPDY checks pass except this notice:

Missing NPN Extension in SSL/TLS Handshake

Sorry, but this server is not including an NPN Entension during the SSL/TLS handshake. The NPN Extension is an additional part of the SSL/TLS ServerHello message which allows web servers to tell browsers they support additional protocols, like SPDY. SSL/TLS servers that don't use send the NPN Extension cannot use SPDY because they have no way to tell the browser to use SPDY instead of HTTP.

What exactly am I missing from Nginx 1.4.1, openssl 1.0.1e and SPDY setup to properly satisfy NPN Extension in SSL/TLS handshake ?

Chrome reports SPDY support fine though.

cheers
