How to Fix Err_cert_authority_invalid
Understanding the Causes of ERR_CERT_AUTHORITY_INVALID
Before diving into solutions, it’s important to understand what triggers this error. Common causes include:
- Expired or invalid SSL certificate
- Browser cache or cookies issues
- Incorrect system date and time
- Antivirus or firewall interference
- Problems with the website’s server configuration
- Issues with the certificate authority (CA) not recognized by your browser
- Using an outdated browser or operating system
Step-by-Step Solutions to Fix ERR_CERT_AUTHORITY_INVALID
1. Check Your System Date and Time
Incorrect system date and time can cause SSL certificates to appear invalid. Follow these steps to verify and correct your system clock:
- Windows: Go to Settings > Time & Language > Date & Time. Ensure “Set time automatically” is enabled and the date and time are correct.
- Mac: Open System Preferences > Date & Time. Check “Set date and time automatically” and select the correct timezone.
After adjusting, restart your browser and try accessing the website again.
2. Clear Browser Cache and Cookies
Corrupted or outdated cache and cookies can interfere with SSL certificate verification. To clear them:
- Google Chrome: Go to Settings > Privacy and security > Clear browsing data. Select “Cookies and other site data” and “Cached images and files,” then click Clear data.
- Mozilla Firefox: Options > Privacy & Security > Cookies and Site Data > Clear Data.
- Microsoft Edge: Settings > Privacy, search, and services > Clear browsing data.
Refresh the page after clearing cache and cookies.
3. Update Your Browser and Operating System
Outdated browsers or OS versions might not recognize newer certificate authorities. Ensure your browser and operating system are up to date:
- Update Browser: Check for updates in your browser settings or download the latest version from the official website.
- Update OS: Use system update features to install the latest patches and security updates.
Restart your device and revisit the website.
4. Disable Antivirus or Firewall Temporarily
Sometimes, security software can block or interfere with SSL certificates. To test this:
- Temporarily disable your antivirus or firewall software.
- Attempt to access the website again.
- If the error resolves, consider adding an exception for the website in your security software settings.
Remember to re-enable your security software afterward to stay protected.
5. Proceed with Caution and Bypass the Error (Not Recommended)
If you’re confident the website is safe, you can bypass the error, but this is risky, especially on unfamiliar sites. In Chrome:
- Click on “Advanced” on the error page.
- Select “Proceed to [website]” (unsafe).
Use this option only if you trust the website and understand the risks involved.
6. Check for a Valid SSL Certificate on the Website
If you own the website or have access to its server, ensure the SSL certificate is valid:
- Verify that the certificate has not expired.
- Confirm that the certificate is issued by a trusted Certificate Authority.
- Ensure the certificate correctly matches the domain name.
- Use online tools like SSL Labs’ SSL Server Test to analyze your website’s SSL configuration.
If issues are identified, renew or reissue the SSL certificate through your hosting provider or certificate issuer.
7. Contact the Website Administrator
If the problem persists on a specific website you do not own, contact the site’s administrator to inform them of the issue. They may need to:
- Renew or reconfigure their SSL certificate.
- Fix server-side issues affecting SSL validation.
Additional Tips for Preventing ERR_CERT_AUTHORITY_INVALID
- Regularly update your browser and operating system to stay compatible with the latest security standards.
- Maintain accurate system date and time settings.
- Use reputable security software and keep it updated.
- Be cautious when bypassing SSL warnings; only proceed if you trust the website.
- Always ensure that the websites you visit use valid SSL certificates from trusted authorities.
