The highlighted dates will give you an idea from where this warning message NET::ERR_CERT_DATE_INVALID is triggered in Google Chrome.
  • Is “Current Date” creating an Issue? Is the displayed current date the actual current date? If not, you have to recognize and troubleshoot issues with your computer.
  • The next thing you have to check is the “Expires on” date. Is the “expires on” date of today or earlier? Generally, it must be of the future.

How to Troubleshoot if the Issue is Due to Current Date?

If you get to know that the error message ERR_CERT_DATE_INVALID is due to the current date, then follow the steps below:
  • First check whether the Date and Time of your computer are set correctly. If not, you will understand why this error has occurred.
  • Restarting your browser can solve this issue. If not, restarting the computer may also work.
  • Check your internet connection. Are you connected to an unsafe Wi-Fi network or some other public network? If that’s the case, then your browser could show you this error message. If that’s the case, stop browsing through that connection and resume from your personal or any reliable connection. If that’s not possible and you have to browse the internet due to some reason, then try to use a trusted VPN.
  • Sometimes the third-party plugins you installed can create issues. Try disabling one by one and once you find out the plugin that is causing the issue, remove it.
  • Clear cache files and the browsing history on your Chrome browser. To do so, click the menu icon, go to History and select “clear browsing data.”
  • Delete your Chrome browser and re-install it. Sometimes, it solves the issue.
  • Not always the case, but sometimes it so happens that your computer might be infected by malware. Scan your computer with a reputed antivirus software.
  • There are some other fixes that are not recommended. But, if you’re sure about the website and its owner, then some of the fixes such as bringing down your firewall protection level or modifying network settings might work. But be sure you’re risking your security for the sake of opening a website, which is not worth it.

If an Expired SSL/TLS Certificate Is the Issue?

If the ERR_CERT_DATE_INVALID error is due to an expired SSL/TLS certificate, then the only solution is to renew the SSL/TLS certificate.

If You’re Not Managing the Website

As a website visitor, you can’t do much. But you can contact the website owner and send them the following.
  • A screenshot showing the NET::ERR_CERT_DATE_INVALID error message
  • Any specific URL of their website, which leads to this error message
  • And a resource to solve the issue. For example, the link to this article

If You’re Managing the Website

If you are the owner of the website or managing on your own, then you need to purchase an SSL/TLS Certificate based on your requirement and renew it.

Conclusion

  • For webmasters, we would say, please recheck your website’s SSL/TLS certificate expiration and renew if it’s expired.
  • Website visitors, follow the above-mentioned steps and if the problem persists, contact the website owner.
