 StartSSL - using a Class 1 certificate again - has an intermediate certificate in their chain, so you have to include this one in your stapling file, too.

 **Update #1**
 
 If you have more than one virtual host with SSL enabled, you have to enable OCSP stapling for every single one. Otherwise nginx will fail silently and not include any stapled OCSP data. (Thanks to [@rmoriz](https://roland.io) for figuring this out)
+
+**Update #2**
+
+This post has been quite popular, so I decided to update it a little bit. The biggest change is that I have removed the certificate chains that were originally included in this post. I did this to not confuse people too much and because I don't want to keep these chains up to date.
+
+The most important thing to remember when setting up OCSP stapling with any CA is to make sure that the entire trust chain (including the root certificate) is included in the `ssl_trusted_certificate` file.
