This message occurred on a third party website some time ago. Now I cannot even access the Google search engine. What do I need to do to clear it?

Full Message: "Your connection is not secure

The owner of www.google.co.uk has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

(Note I am reporting this through MS Edge. I cannot access anything on Firefox))

Are you using Kaspersky security software?

See:

You can click the "Advanced" button to expand this section and show extra details. If the certificate is not trusted because the issuer certificate is unknown (SEC_ERROR_UNKNOWN_ISSUER) then click the blue error message to expand this section and show the certificate chain. You can click "Copy text to clipboard" and paste the base64 encoded certificate chain text in a reply. That will allow us to details like the issuer of the certificate.

  • always be cautious when you get an 'Untrusted' error message
  • never create a permanent exception without investigating the cause and only use this to inspect the certificate
