Support for Internet Explorer 11 has ended on June 15, 2022

Internet Explorer 11 will no longer be accessible after February 14, 2023. If any site you visit needs Internet Explorer 11, you can reload it with Internet Explorer mode in Microsoft Edge. We recommend you use Microsoft Edge  for a faster, more secure and more modern web browsing experience.

Get started with Microsoft Edge

Occasionally you'll get an error message telling you there's a problem with a website's security certificate. A site's certificate allows Internet Explorer to establish a secure connection with the site. Certificate errors occur when there's a problem with a certificate or a web server's use of the certificate. Internet Explorer helps keep your information more secure by warning about certificate errors.

Error message

What it means

This website's security certificate has been revoked

You shouldn't trust this website. This often means that the security certificate was obtained or used fraudulently by the website.

This website's address doesn't match the address in the security certificate

A website is using a certificate that was issued to a different web address. This can occur if a company owns several websites and uses the same certificate for multiple websites.

This website's security certificate is out of date

The current date is either before or after the time period during which the certificate is valid. Websites must renew their certificates with a certification authority to stay current. Outdated certificates can be a security risk.

This website's security certificate isn't from a trusted source

The certificate has been issued by a certification authority that isn't recognized by Internet Explorer. Phishing sites often use fake certificates that trigger this error.

Internet Explorer has found a problem with this website's security certificate

Internet Explorer found a problem with a certificate that doesn't match any other errors. It could be because a certificate has been damaged, tampered with, written in an unknown format, or is unreadable. You shouldn't trust the identity of the site if a certificate has this error.

A website's certificate provides identification of the web server. If the certificate has an error, it might indicate that your connection has been intercepted or that the web server is misrepresenting its identity. If you're absolutely positive of the website's identity, you know that your connection hasn't been compromised, and you understand the risks, you can choose to go to the website. However, we recommend that you don't ignore a certificate warning.
 

Yes. While this isn't recommended, you can select Continue to this website (not recommended) on the certificate error warning page to go to the website. If you ignore the warning page and go to a site that's presented a certificate containing an error, Internet Explorer will remember the certificate while you have your browser open. You can return to the site without receiving another warning for that certificate until Internet Explorer is restarted.
 

No, you can't turn off certificate checking in Internet Explorer. If you receive certificate errors, it means the website you're visiting is having certificate problems and it doesn't indicate a problem with Internet Explorer.
