Hi

I am trying to access a site with a self signed certificate and there is no option to add a security exception. Get this code: SEC_ERROR_UNKNOWN_ISSUER

Have added a security exception through settings but still can't access the site.

What is going on??

Can you post the certificate data?

You can check if there is more detail available about the issuer of the certificate.

  • click the "Advanced" button show more detail
  • click the blue error text (SEC_ERROR_UNKNOWN_ISSUER) to show the certificate chain
  • click "Copy text to clipboard" and paste the base64 certificate chain text in a reply

If clicking the blue error text doesn't provide the certificate chain then try these steps to inspect the certificate.

  • open the Servers tab in the Certificate Manager
    • Options/Preferences -> Privacy & Security
      Certificates: View Certificates -> Servers: "Add Exception"
  • paste the URL of the website (https://xxx.xxx) in it's Location field

Let Firefox retrieve the certificate -> "Get Certificate"

  • click the "View" button and inspect the certificate

You can see detail like the issuer of the certificate and intermediate certificates in the Details tab.

This issuer of the certificate is DDoS-Filter.domain. A Google search brings up results like these that seem to indicate that this is a problem with the website that is protected with some DDos protection service that may not work properly and their certificate is send instead of the certificate from the website.
