3 Ways to Fix Certificate Validity Too Long in Chrome
A certificate is valid for a period of time determined by the CA
- Certificate Validity Too Long is a common error that occurs when you visit a website using Chrome or Firefox.
- When you visit a website, your browser checks if the site’s certificate is valid before you can proceed.
- Since certificates expire, you may come across problems connecting to sites.
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 to ignore certificate errors.

- Changes to your Internet connection – Sometimes, when you change your router settings, firewall, or security software settings on your computer, it can cause problems with how secure sites are accessed.

How long can a certificate be valid?

1. Update your system time
Expert tip:

Some PC issues are hard to tackle, especially when it comes to missing or corrupted system files and repositories of your Windows.
Be sure to use a dedicated tool, such as Fortect, which will scan and replace your broken files with their fresh versions from its repository.
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
- Hit the Windows key, type Control Panel in the search bar and click Open.
- Navigate to Network and Internet.
- Click on Internet Options.
- Go to the Content tab and hit the Clear SSL state button.
- Retry your site again.
How to disable certificate check in Chrome?
The SSL certificate check is a security feature that helps protect people who visit your website. It prevents your website from being impersonated and encrypts information sent between you and your visitors.
However, it can easily become a nuisance if it continuously blocks websites that are not harmful. You can disable this feature for development purposes or during testing to allow any site to open in Chrome.
Disabling the certificate check will allow you to access blocked sites and download otherwise inaccessible content. To do so, follow the steps below:
- Find the Google Chrome shortcut on your Desktop, right-click on it and select Properties.
- Navigate to the Target string and add the following string at the end:
--ignore-certificate-errors
- Press OK to effect the changes.
