In this article, we will discuss the steps to fix this error and ensure a smooth browsing experience.
Understanding the Error
Before diving into the solutions, it is essential to understand the root cause of the “err_cert_authority_invalid” error. This error occurs when the web browser encounters a certificate issued by an authority that is not recognized or trusted. The certificate authority (CA) is responsible for validating the identity of the website and ensuring that the connection is secure. If the CA is not recognized, the browser will display the “err_cert_authority_invalid” message.
Steps to Fix the Error
1.
Check the Date and Time
One of the most common reasons for encountering the “err_cert_authority_invalid” error is a misconfigured date and time on your device. Ensure that your computer’s clock is set correctly. If the date and time are incorrect, it can cause the browser to reject the certificate as expired or invalid.
2.
Update Your Browser
Outdated browsers may not support the latest security protocols and certificates. Make sure that your browser is up-to-date by visiting the official website of your browser and installing the latest version.
3.

Check the Certificate Store
If the certificate authority is not recognized, it might be due to a missing or corrupted certificate in the certificate store. To fix this issue, follow these steps:
– For Windows:
