Ubuntu – Why does Android Chrome say the site’s security certificate is not trusted

androidgoogle-chromehttpsssl-certificateUbuntu

My site is https://blendbee.com. It's using a PositiveSSL certificate that is valid.

In Windows 8 Chrome the certificate is fine (green lock in top left corner).

But…on my Android, it's not so fine. Screenshot: http://postimg.org/image/6vc64lr1d/

Any ideas why?

The server is running Ubuntu 13.10 at Digital Ocean.

You need to provide the entire certificate chain in order for it to show up as trusted.

Here's the link I got for comodo's instructions on installing the cert chain in apache: https://support.comodo.com/index.php?/Default/Knowledgebase/Article/View/637/37/certificate-installation-apache--mod_ssl

I got this from http://www.sslshopper.com/ssl-checker.html#hostname=blendbee.com, which flagged your cert as not being trusted in all browsers because of an incomplete chain.
