Learn how to troubleshoot and fix the ERR_CERT_AUTHORITY_INVALID error and SSL certificate issues. These problems can arise due to self-signed certificates, expired certifications, system clock inaccuracies, or even antivirus or network interference. Follow this practical guide to diagnose and resolve the issue effectively.
Recognizing the ERR_CERT_AUTHORITY_INVALID Error
The ERR_CERT_AUTHORITY_INVALID error is a common browser warning indicating that the website's SSL certificate cannot be validated. The message usually reads:
- "Your connection is not private," accompanied by
ERR_CERT_AUTHORITY_INVALID.
This issue commonly occurs when:
- The SSL certificate is self-signed or improperly issued.
- The certificate is expired or incorrectly installed.
- The system clock is misaligned.
- Antivirus software or a firewall is interfering with the SSL connection.
- Network issues or DNS settings are causing errors.
What Causes SSL Certificate Errors?
SSL certificate errors, such as ERR_CERT_AUTHORITY_INVALID, arise due to several factors:
- Untrusted Certificate Authority (CA): The browser cannot verify the issuing authority of the SSL certificate.
- Invalid or Expired Certificates: Websites using outdated or improperly configured SSL certificates trigger warnings.
- Incorrect System Clock Settings: SSL authentication relies on accurate device time settings. Misaligned clocks can break the verification.
- Network or DNS Interference: DNS misconfigurations or third-party network tools, such as proxy or VPN software, may block SSL connections.

Resetting the Windows Winsock Catalog to Fix DNS Issues
If DNS-related issues are suspected, resetting the Winsock catalog and flushing the DNS cache can often resolve the problem.
Reset Winsock and Flush DNS
netsh winsock reset
# Successfully reset the Winsock catalog. You must restart the computer to complete the reset.
ipconfig /flushdns
# Successfully flushed the DNS Resolver Cache.After running these commands, restart your computer to apply the changes.
How to Perform a Complete Network Settings Reset
If resetting Winsock and DNS does not resolve the issue, a full network reset may be necessary. Follow these steps:
steps
- Open the Start menu and search for "Network Reset."
- Open the "Network Reset" settings.
- Select the Reset Now button and confirm the action when prompted.
- Restart your PC to complete the process.
Note: This action removes all network settings, including saved Wi-Fi passwords. Ensure you have them backed up before proceeding.
Tips for Renewing Expired Certificates
Expired or incorrectly installed SSL certificates often trigger the ERR_CERT_AUTHORITY_INVALID error. Here are tips for addressing this issue:
Regular renewal and monitoring of certificates can prevent expired SSL errors in the future.
Verification Once Fixed
Once you've followed the steps above, verify if the error is resolved:
FAQ
How can I fix the ERR_CERT_AUTHORITY_INVALID error in Google Chrome?
To fix the error, start by checking your system clock and synchronizing it. Clear your browser cache, run a DNS flush, and ensure your antivirus or firewall isn’t blocking SSL connections. If visiting your own website, verify the SSL certificate is valid and issued by a trusted authority.
Why does my browser not recognize a self-signed certificate?
Most browsers do not trust self-signed certificates by default because they are not issued by a recognized Certificate Authority (CA). Add the self-signed certificate to your system's trusted CA store or switch to a certificate from a trusted authority like Let's Encrypt.
Can antivirus software cause SSL errors?
Yes, some antivirus programs intercept SSL traffic for scanning purposes, which may result in certificate errors. Temporarily disable HTTPS scanning features in your antivirus to see if it resolves the issue.
What tools can confirm if an SSL certificate is valid?
Services like SSL Labs Test allow you to test the validity, expiration, and configuration of SSL certificates for any website.
