Troubleshooting Microsoft Edge Certificate Error

Last Updated: Feb 5, 2024 by

Microsoft Edge is a popular web browser that comes pre-installed on Windows 10 devices. It offers a fast and secure browsing experience, but like any other browser, it can encounter errors. One common error that users may encounter is the Microsoft Edge certificate error. This error can prevent users from accessing certain websites and can be frustrating to deal with. In this article, we will discuss what causes this error and how to troubleshoot it.

Understanding the Microsoft Edge Certificate Error

The Microsoft Edge certificate error occurs when the browser is unable to verify the identity of a website’s SSL certificate. SSL (Secure Sockets Layer) is a security protocol that encrypts data between a user’s browser and a website, ensuring that sensitive information is protected. When a website’s SSL certificate is not recognized or is expired, Microsoft Edge will display a warning message stating that the connection is not secure.

Causes of the Microsoft Edge Certificate Error

There are several reasons why the Microsoft Edge certificate error may occur. Some common causes include:

  • Expired or invalid SSL certificate: If a website’s SSL certificate has expired or is not recognized by Microsoft Edge, the browser will display the certificate error.
  • Incorrect date and time settings: If the date and time on your device are incorrect, it can cause issues with SSL certificates.
  • Antivirus or firewall settings: Some antivirus or firewall settings may interfere with the SSL certificate verification process, causing the error to occur.

Troubleshooting the Microsoft Edge Certificate Error

If you encounter the Microsoft Edge certificate error, here are some steps you can take to troubleshoot it:

Check Date and Time Settings

The first thing you should do is check the date and time settings on your device. If they are incorrect, adjust them and try accessing the website again.

Clear Browsing Data

Sometimes, cached data and cookies can cause issues with SSL certificates. To clear your browsing data in Microsoft Edge, follow these steps:

  1. Click on the three dots in the top right corner of the browser.
  2. Select “Settings” from the drop-down menu.
  3. Under “Clear browsing data,” click on “Choose what to clear.”
  4. Check the boxes next to “Cookies and saved website data” and “Cached data and files.”
  5. Click on “Clear.”

Disable Antivirus or Firewall Temporarily

If you have antivirus or firewall software installed, try disabling it temporarily and see if the error persists. If the error goes away, you may need to adjust the settings of your security software to allow Microsoft Edge to verify SSL certificates.

Update Microsoft Edge

Make sure you have the latest version of Microsoft Edge installed. Updates often include bug fixes and security patches that can resolve issues like the certificate error.


The Microsoft Edge certificate error can be a frustrating issue, but by following these troubleshooting steps, you should be able to resolve it. If the error persists, you may need to contact the website’s administrator or your IT department for further assistance. By keeping your browser and device up to date and checking your date and time settings, you can prevent this error from occurring in the future.
