Question
Simple SPDY implementation not working

Hello,
Wonder if you could help - I’m having an issue where the instructions to just ‘flip the spdy switch’ aren’t working for me.
Here’s the setup:
Ubuntu 12.04 LTS Nginx 1.7.12 (upgraded today from Ubuntu mainline/dev PPA - includes ssl modules) OpenSSL 1.0.1 (build from 19/03/15 - upgraded today) Have restarted Dovecot/Postfix/PHP5-FPM/Monit and of course Nginx.
Spdycheck.org is showing no spdy due to no NPN (but this version of openssl supports it, checked changelog), the Chrome/FF extensions also reporting no spdy. SSL Labs are reporting ‘No’ for NPN.
Also trying to get HSTS working with no joy either. Using the line below.
Where am I going wrong?
I have included the following in the sites-enabled host file, for the https server block:
listen 443 ssl spdy default_server;
[server_name, limit_con, log, keepalive_timeout, ssl certs…]
add_header Strict-Transport-Security “max-age=31536000; includeSubDomains”; add_header Alternate-Protocol 443:npn-spdy/3; I’m seeing nothing about the latter two headers in the Network section of the Chrome/FF [F12] profilers.
Thanks!

UPDATE:
Fixed / resolved / working - rebooting the server fixed it. Restarting each service individually didn’t work. I might have missed one, despite restarting mysql, ssh, nginx etc. etc.
Now HSTS etc. all working too. No idea why they wouldn’t work previously.
For info, this is the version of openssl being used:
https://launchpad.net/ubuntu/+source/openssl/1.0.1-4ubuntu5.25
Thanks for sharing that, @jtittle - I took the parts I didn’t have yet (stapling, the ‘ssl on’ line) and re-ordered the headers so that the Alternate-Protocol came before the STS line. Nothing changed. It’s still not being read by nginx.
Something in my config is either overriding it or getting there first.
SSL Labs still reporting no HSTS, no stapling, no NPN (thus, no spdy!).
Error logs only showing some md5 cache collisions - will keep looking.
