How to Fix ERR_BAD_SSL_CLIENT_AUTH_CERT for Google Chrome?

Google Chrome is one of the most popular browsers across the globe. As per the Statista site, Google Chrome covers almost 47.91% share of the overall internet browser market in the U.S. But this browser displays various errors, preventing users from accessing content on the website. One such error displayed by the Chrome browser is ERR_BAD_SSL_CLIENT_AUTH_CERT.

Cause of ERR_BAD_SSL_CLIENT_AUTH_CERT Error:

This error is related to SSL certificates. When any user tries to access a website on the internet, Google Chrome tries to check the SSL certificate installed on the site for security reasons. If the Chrome browser is unable to open the respective URL entered by the user, then the above error message will be displayed by the browser. Chrome is concerned about the web safety of its users and hence this browser does not accept SSL security certificates issued by non-trustworthy Certificate Authorities.

This issue was investigated and there turned out to be multiple reasons and factors responsible for triggering ERR_BAD_SSL_CLIENT_AUTH_CERT error.

A few of the common strategies which can resolve this error are mentioned below.

1. Sync the Date & Time:

One of the most common reasons which cause the above-mentioned SSL error is the erroneous date and time displayed on the computer. Incorrect date and time displayed on Windows 10 may tend to create conflicts.

4. Check for Third-Party Software Conflicts:

Third-party software mainly for web protection include anti-virus software, firewall, etc. may create a conflict with the SSL/TLS certificate and tend to cause ERR_BAD_SSL_CLIENT_AUTH_CERT error.

They may perceive that the web page approached by the user is compromised and may block the same on the browser.

Solutions:

Step #1: Check all third-party software’s installed on your computer like VPN, anti-virus software, firewall, or any other web security software which may disrupt navigation.

Step #2: Disable all these software’s temporarily and eradicate your root problem.

5. Change TLS/SSL QUIC Settings:

Sometimes protocol fixes for SSL/TLS may cause cipher mismatch and lead to this error. It is advisable to follow the fixes to resolve the same.

Solutions:

Step #1: Try to disable previous TLS versions like TLS1.1 and TLS1.2 and enable SSL2 and SSL3, if that helps. Click save and check.

Step #2: Disabling of QUIC protocol method may also help erase this SSL error. Type “chrome://flags/#enable-quic” in the address bar and later click Enter.
