Key notes

Sometimes, your Chrome browser may display a certificate error on a website. This error message is related to the certificate validity period, meaning that the website’s SSL certificate has expired or will expire soon.

If you see this error, you must update your browser’s root certificate store so it can trust the site again. Your computer uses an SSL certificate to verify that you’re connecting to the correct site and not being redirected to a phishing site or another malicious website.

In general, if your web browser warns you about an expired certificate, you should not trust that website until you have confirmed that it is still safe. If you are in a hurry and don’t have time for verification, you can choose toignore certificate errors.

How can I fix the Chrome certificate validity too long error?

How can I fix the Chrome certificate validity too long error?

1. Update your system time

If the clock on your computer is not in sync with the server, it could result in a wrong certificate expiration date. Once Chrome detects your computer’s clock is incorrect, it will display an error message.

This may have happened if you have traveled recently and not reset your time and date settings to your current time zone. You can manually do so through the control panel.

2. Update your OS/browser

This is probably the easiest solution, but if you haven’t updated your operating system in a while, it might be time to do so. Using an older version of Windows or macOS may bring up bugs and errors with third-party software such as Chrome.

If you’ve updated your OS and still have issues with Chrome not loading websites properly, it might be time for another update — specifically for Chrome itself.

This can happen if there are bugs in the browser code itself or if security updates are needed to ensure that users’ data remains safe from hackers trying to steal login information and other sensitive data.

3. Clear SSL cache

Disabling the certificate check will allow you to access blocked sites and download otherwise inaccessible content. To do so, follow the steps below:
