I’m seeing the “ERR_CERT_AUTHORITY_INVALID” error when visiting some websites. What causes this, and what steps can I take to safely resolve it so the site loads properly?

Check your date/time, clear cache, disable VPN or antivirus, update Chrome, or avoid the site if the certificate is unsafe.

Try these user-side actions:

• Sync the time and date on your computer (common fix).
• Clear the cookies and cache in Chrome.
• Update to the most recent version of Chrome.
• Turn off the SSL scanning on your VPN and antivirus software temporarily.

This error means Chrome doesn’t trust the site’s security certificate. You can fix it by checking your device date/time, clearing browser cache, disabling VPN or antivirus temporarily, and updating Chrome. If it’s your website, install a valid SSL certificate through a trusted provider. Avoid proceeding on unknown sites to stay secure.
