SSL OCSP stapling won't enable

Sat Dec 14 07:06:29 UTC 2013

According to ssllabs.com SSL OCSP stapling is not enabled, even though I
have the following in my http block:

  ssl_stapling on;
  ssl_stapling_verify on;
  ssl_trusted_certificate /etc/pki/tls/certs/ca-bundle.trust.crt;
  resolver 8.8.4.4 8.8.8.8 valid=600s;
  resolver_timeout 15s;

Any idea why? Here is my full ssllabs.com report:
