Google Chrome web browser checks the SSL Security Certificate of the web page that the user is trying to access. If it is unable to then one error related to SSL Certificates which a user may face while browsing with Chrome is ERR BAD SSL CLIENT AUTH CERT. This can be caused due to many factors like the computer’s Time, and Date is out of sync, Cached Data is corrupt, third-party software installed on the computer is blocking the site, etc.
The cause could also be at the website’s end. The server is rejecting the certificate the client website is sending. It could have expired, or the server may not trust its issuer. Nevertheless, there are a few things you could try at your end. To fix this error, we will be taking a look at the following methods-
- Update Google Chrome.
- Sync Date and Time.
- Clearing browser data.
- Checking and fixing any third-party software conflicts.
- Change TLS/SSL3 and QUIC settings.
1] Update Google Chrome
You can try to get the latest version of Google Chrome and have it installed on your computer and check if that fixes your issue.
2] Sync Date and Time
Wrong Date and Time settings on Windows 10 can also cause conflicts like this. This is due to the incompatibility between the SSL Certificate validation date and the System Clock. Hence, the user should sync their System Clock.
To do this, start by right-clicking on the Taskbar and click on Adjust Date and Time.
Click on a button that says Sync Now. It will synchronize the Date and Time with the Microsoft Servers.
All you need to make sure is that the Time Zone set on the same page is correct.
3] Clear browser data
There are high chances that some browser data is conflicting with the loading of the website. This might be a very basic fix, but in this case, it can be proved a highly reliable one.
For this, start by opening Google Chrome. Now hit the CTRL + H button combination on your keyboard.
This will open a new panel to delete your browsing history and other data. Select every checkbox that you see and finally click on Clear browsing data.
Restart your browser and check if your error is fixed or not.
4] Check and fix any third-party software conflicts
Third-party internet protection software like Antivirus can also be a cause for this error. Due to some reason they might be detecting the web page to be malicious or with less credibility. And hence, this might be blocking the web page on your web browser. So, to fix that, I would suggest you to see if any third-party software like VPN, Security software or an add-on may be interfering and turn it off. You could open your antivirus software and temporarily disable web protection and see if that helps.
5] Change TLS/SSL3 and QUIC settings
As a temporary measure you may try disabling TLS1.1 & TLS1.2 and enabling SSL2 & SSL3 and see if that helps.
Follow the protocol fixes for SSL3/TLS and QUIC which are some of the reasons to cause the error. If your antivirus or security software offers this setting, you may disable “SSL/TLS” protocol filtering and see.
Are these fixes effective?
