Why is my certificate not trusted?
There are many reasons why a certificate may not be trusted. The exact problem is indicated on the report card in bright red. The problems fall into three categories:
- Invalid certificate
- Invalid configuration
- Unknown Certificate Authority
You say "SSL Labs does not maintain its own trust store; instead we use the store maintained by Mozilla", but I cannot find that store. When I click the link "Client Certificates" at http://www.mozilla.org/projects/security/pki/psm/help_21/using_certs_help.html, it returns an error saying that it cannot connect to certs.netscape.com
Mozilla itself does not complain about the certificate and it was issued by a well known authority
How can I find out why this certificate is not trusted?
