Fix "Your connection is not private" in Google Chrome

What does it mean?

Websites use SSL to lock the link between you and the site. SSL uses a certificate, which is a digital ID card for the site. When Chrome cannot trust that card, it stops you and shows "Your connection is not private". The error code under it, such as NET::ERR_CERT_DATE_INVALID, tells you why.

If you are a visitor

1. Reload the page. Sometimes it is a short glitch.
2. Check your computer's date and time. A wrong clock is a very common cause. Fix it and reload.
3. Open the page in a private (Incognito) window. If it works, a browser add-on or cache is the problem.
4. Clear the cache. Press Ctrl+Shift+Delete, choose cached images and files, and click Clear data.
5. Turn off any VPN, antivirus web shield or proxy for a moment and try again.
6. Avoid public Wi-Fi that asks you to log in. Open the login page first.
7. If you only see it on one site, do not enter passwords or card details on it.

Warning: do not click Proceed (unsafe) on sites that ask for passwords or money.

If you own the site

1. Log in to cPanel and open SSL/TLS Status.
2. Check that your domain has a valid certificate that has not expired.
3. If it is missing or expired, click Run AutoSSL or install a new certificate.
4. Check that the certificate covers both example.com and www.example.com.
5. Make sure the CA bundle is installed. The bundle links your certificate to a trusted company.
6. Do not use a self-signed certificate on a public site. Browsers do not trust it.
7. Wait a few minutes after any change and test in a private window.

Common error codes

Quick recap

• The warning means Chrome cannot trust the site's certificate.
• Visitors: fix the clock, clear the cache, try Incognito.
• Owners: renew or install a valid certificate with the bundle.
• Never enter private data on a site that shows this warning.
