What is Fix Err_Certificate_Transparency_Required and How to Deal With This Error

An invalid certificate transparency information error occurs specifically in Google Chrome and mainly relates to problems with your SSL certificate. As a result, this issue might cause some serious troubles in the future, namely data theft and financial fraud. In this post, we'll explain what the err_certificate_transparency_required error means, what triggers it, and how you can promptly react to it.

What does ERR_Certificate_Transparency_Required mean?

Google Chrome users may sometimes stumble upon the message that states: "No certificate transparency information was supplied by the server." This error prevents you from accessing a website, no matter if it’s your own or not. Most commonly, you may experience it if there are issues with the SSL certificate of a given website.

As an encryption protocol, SSL ensures the security of the information transmitted between your browser and a website’s server. In other words, it blocks third parties from stealing any data entered into a site. SSL is a widespread security measure among eCommerce or banking platforms that handle sensitive information such as users' credit card details.

To make this certificate properly work, you have to install it on your website: you can either get one within your hosting plan or buy it from an issuing authority. Furthermore, you'll need to make sure to add your certificate to the Certificate Transparency log. This framework backs up these certificates' security as it helps domain owners see and manage their certificates and identify unauthorized ones.

You see the err_certificate_transparency_required error message when you attempt to enter HTTPS websites with SSL/TLS-related errors. Such errors worsen the connection between your device and a remote server.

What causes the ERR_Certificate_Transparency_Required error

The most popular reason that triggers the err_certificate_transparency_required Chrome issue is that the SSL certificate of a website isn't in the transparency log created by the issuing authority.

Here's what can trigger this error:

  • The site owner might have asked the authority not to include the certificate into the log.
  • The issuing authority has not added the certificate, most likely because of a mishap.
  • Improper installation of the site’s SSL certificate.
  • A corrupted SSL certificate.
  • An expired certificate has expired.

There are, however, several possible solutions to the issue too. Below is a list of the most efficient ones:

  1. Contact the certificate issuing authority. There might have been an error, and they hadn't added your SSL certificate to the Certificate Transparency log.
  2. Apply the Certificate Transparency exemption policy to let users access your website. This will remove your domain and / or subdomain from the Certificate Transparency log so that users will be able to access a website without stumbling upon the ERR_Certificate_Transparency_Required message.
  3. Reissue and reinstall your SSL certificate to make sure it's properly set up.

If you're seeing this issue as a website user, try the following:

  1. Ignore this error;
  2. Contact the website owner;
  3. Clear the SSL slate;
  4. Delete cookies and cached data in Chrome;
  5. Disable Google Chrome extensions;
  6. Disable firewall and antivirus apps;
  7. Update Google Chrome.
