The NET::ERR_CERT_AUTHORITY_INVALID error is a common issue encountered by users when trying to access a secure website. This error typically indicates a problem with the site’s SSL certificate. Whether you are managing a website on a VPS hosting plan, securing your domains with SSL certificates, or running a more complex platform on a dedicated server, understanding how to resolve this error is essential for ensuring a seamless user experience.

Why Does the NET::ERR_CERT_AUTHORITY_INVALID Error Occur?

This error can be caused by several factors, including:

  • An expired or self-signed SSL certificate.
  • A certificate authority not recognized by the browser.
  • Incorrect SSL certificate configuration.
  • An unsecured connection or network misconfiguration.

How to Fix the NET::ERR_CERT_AUTHORITY_INVALID Error

1. Check SSL Certificate Validity

Ensure that your SSL certificate is still valid. You can check this by clicking on the padlock icon next to the URL and viewing the certificate details.

2. Renew Your SSL Certificate

If your SSL certificate has expired, you need to renew it through your certificate authority or hosting provider.

3. Verify SSL Certificate Configuration

Make sure that your SSL certificate is properly installed and configured on your web server. Some browsers may reject misconfigured certificates.

4. Check Your Device’s Date and Time

An incorrect date or time on your computer can cause SSL errors. Ensure your system’s date and time are correctly set.

5. Clear SSL Cache and Browser Cookies

Browsers store SSL certificates and may cause errors if outdated information is used. Try clearing your SSL cache and deleting cookies.

6. Temporarily Disable Browser Extensions

Certain browser extensions can interfere with SSL connections. Try disabling extensions temporarily and reload the page.

7. Use a Different Network

If you are using a public or corporate Wi-Fi network, certain network restrictions may block SSL certificates. Try switching to another network to see if the issue persists.

Preventing the NET::ERR_CERT_AUTHORITY_INVALID Error in the Future

  • Use an SSL certificate from a recognized certificate authority.
  • Ensure your server is correctly configured to use HTTPS.
  • Regularly update your SSL certificate before it expires.
  • Check your network configuration and avoid suspicious proxies.
  • Consider using managed hosting for automatic SSL management and security updates.
