Detailed Explanation: What is the ERR_CERT_DATE_INVALID Error?

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

The browser will then validate the installed certification to ensure that it withholds all updated privacy standards. 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 users.

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