Error: err_cert_authority_invalid

Educative Answers Team

err_cert_authority_invalid is an error that indicates that your browser (e.g., Google Chrome) does not trust the SSL Certificate of the website. Possible reasons for a browser not trusting a certificate are:

  • The Certificate Authority (CA) that issued the certificate is not trusted.
  • The certificate is self-signed.

Most browsers will display a warning preventing the user from visiting such a website as websites whose certificates cannot be trusted are prone to man-in-the-middle (MITM) attacks.

Solution for users

The best solution is to contact the website owner to inform them that their certificate is invalid.

However, if you are sure that you can trust the website and there is no possibility of a MITM attack, you can proceed to visit the website by clicking on ‘Advanced’ and then ‘Proceed to [website name]’ in Google Chrome.
You can also manually import the root certificate telling your browser that the SSL certificate was issued from your system. We recommend you only follow these workarounds if you know what you are doing and accept the risks involved.

Solution for website owners

If you are the owner of the website and facing the above issue, you need to get the certificate issued from a trusted Certificate Authority (CA)e.g., Symantec or DigiCert. Self-signed certificates save you money, but users’ browsers cannot trust your certificate unless it is issued by a trusted CA.
