Firefox and SSL: sec_error_unknown_issuer

Tags:

firefox

My client gets a sec_error_unknown_issuer error message when visiting https://mediant.ipmail.nl with Firefox. I can't reproduce the error myself. I installed FF on a Vista and a XP machine and had no problems. FF on Ubuntu also works fine.

Does anyone get the same error and does anyone have some clues for me so I can tell my ISP to change some settings? The certificate is a so called wild-card SSL certificate that works for all subdomains (*.ipmail.nl). Was I wrong to pick the cheapest one?

Why is SSL not working in Firefox?

Secure Connection Failed Firefox Error Secure Connection Failed on Firefox error comes up when the browser does not recognize the Certificate Authority (CA) associated with the SSL certificate. However, this matter can be resolved by adding a new CA in the browser.

Just had the same problem with a Comodo Wildcard SSL cert. After reading the docs the solution is to ensure you include the certificate chain file they send you in your config i.e.

SSLCertificateChainFile /etc/ssl/crt/yourSERVERNAME.ca-bundle
