I can't get spdy to work after reinstalling Ubuntu. I'm using nginx 1.5.9 from the nginx launchpad repository which has spdy support build in. Snippet:

root@ssl:/etc/nginx/# nginx -V
nginx version: nginx/1.5.9
TLS SNI support enabled
configure arguments: …. --with-http_spdy_module ...

My vhost is configured as followed:

server {
    listen 443 ssl spdy;

    ssl on;
    ssl_certificate     /etc/nginx/ssl/ssl-bundle.crt;
    ssl_certificate_key /etc/nginx/ssl/ssl-bundle.key;

    location / {
     root /var/www;

    access_log /var/log/nginx/access.log  combined;
    error_log  /var/log/nginx/error.log debug;
  • I already tried adding the spdy header (which shouldn't be necessary anymore) without luck
  • The website loads fine
  • My https certificate is valid, all browser give me a green lock-symbol
  • SPDY doesn't work in the latest chrome or firefox

How can I further debug the spdy plugin? Any tips for further configuration?

What Ubuntu version do you have? Is there anything in nginx error log on startup or after the request? – Tero Kilkanen Apr 16 '14 at 12:03
I'm using 13.04. Here are the debug-logs for the vhost. Can't find anything spdy related in it though. – user196611 Apr 16 '14 at 12:10
Remember to get rid of 13.04. It's past end of support already. – Michael Hampton Apr 17 '14 at 17:47

It turned out that Firefox & Chrome only support spdy 3, and nginx 1.5.9 still has spdy1/2. Upgrading to nginx/1.5.12 fixed my issue
