The error 'NET::ERR_CERT_AUTHORITY_INVALID' occurs when Internet Explorer (IE) and Google Chrome are unable to verify the SSL certificate of a website, but Firefox is able to access it without issues. This issue affects users who rely on IE and Chrome for browsing and may be frustrating due to the inability to proceed past the certificate error.

In this guide, we will explore the root causes of this error, provide primary and alternative fix methods, and offer step-by-step instructions to resolve the issue.

⚠️ Common Causes

  • The primary cause of this error is that IE and Chrome are not configured to use system proxy settings. By default, these browsers do not inherit system-wide proxy settings from Windows or other applications. This can lead to a lack of connectivity issues with certain websites, especially those using SSL certificates.
  • An alternative reason for this issue could be related to the Advanced Security settings in IE. While changing these settings may provide temporary fixes, they may not address the underlying cause of the problem.

  5. Step 5: Step 5: Repeat steps 1-4 for Google Chrome by navigating to chrome://settings/ > Advanced > System > Change proxy settings.
