Fix "Your connection is not private" error
If you see a full-page error message saying "Your connection is not private," then there's a problem with the site, the network, or your device. Learn how to troubleshoot "Your connection is not private" errors.
What a security certificate is
When you go to a site that uses HTTPS (connection security), the website's server uses a certificate to prove the website's identity to browsers, like Chrome. Anyone can create a certificate claiming to be whatever website they want.
To help you stay on safe on the web, Chrome requires websites to use certificates from trusted organizations.
