The err_cert_date_invalid error is mostly seen in sites that run on HTTPS (or should be running on it). Whenever you visit a new web page, the browser will first send a request to the server where the site is being hosted.

The browser will then validate the certification installed to make sure that it is withholding all updated privacy standards. Some other things that are checked include the decryption of the certificate, the authorized body checking the certificate, and the TLS handshake.

If the browser finds out that a particular website is not valid, it will try to prevent you from visiting that page. Most popular browsers today are fitted with this feature to protect the users.

If the certification has not been set up as it should, it means that the web page has not been encrypted as it should, thereby rendering the site as unsafe, especially for those that process payment information or with logins. In this case, you will be greeted by a message that reads, ‘your connection is not private.’
