"This site is not secure" and similar errors can prevent you from visiting some web pages. This article discusses simple methods for diagnosing the problem, gauging your level of risk, and mitigating any potential security hazards.

How to Fix 'Not Secure' Connection Errors

There's nothing you can do if the problem is on the website's end. If the issue is coming from your device, here are some solutions to try:

1. Reload the page. This is a quick and easy troubleshooting option to try. If refreshing the page doesn't help, restart the whole browser by closing it (don't just minimize it) and reopening it.

2. Check the URL to make sure the address was typed correctly. Any small typo could result in the wrong page trying to load, which could lead to a "connection not secure" or similar error.

3. Clearing your browser cacheand cookies is another quick, easy troubleshooting method that may solve the problem.

4. Update your browser. Outdated browsers may have security holes that updates will fix. For most browsers, you can check if you're using the latest edition through a Help or About menu.

5. Disable all your browser extensions. One or more could be causing security or network issues that result in this error.

6. Disable the VPN if you're using one. VPNs complicate how your data is routed through the internet, which can cause some websites to throw a "not secure" connection error.

7. Check if the page loads on a different network. For example, if the connection to the site is not secure when using Wi-Fi on your phone, switch over to mobile data. If you don't see the error, reboot your router; the issue could be related to your network.

8. Scan for malware. You could have an infection if you're seeing the error when attempting to visit major websites like Google and Wikipedia, and especially if other devices on your network are not experiencing this issue.

9. Check your AV software. Features like a firewall can sometimes conflict with your network settings and mistakenly block some SSL certificates and connections. To see if this is the problem, temporarily disable your antivirus software's SSL scanning feature.

10. Fix your computer's date and time. If incorrectly set, it can prevent your browser from verifying the SSL certificate of the site you're visiting.

11. Use HTTPS Everywhere. Most browsers have this feature enabled by default but check the app's privacy settings to be sure.

    

12. Use an SSL certificate checker. Third-party SSL certificate checkers, such as SSL Server Test, will tell you everything about the flagged site, from its IP address to the certificate issuer and expiration. What you find will tell you if the site's problem is simple or more complicated.

13. Reset your router. If your router has been compromised, restoring it to its factory default settings can clear it out. All routers work a little differently, but look for a reset button or hole on the back or bottom.

Can I Ignore the 'Not Secure' Error?

If you feel confident that the error is on the part of the website, and the website is known and trusted, and if the site doesn't include any functionality where sensitive personal data passes back and forth, you can choose to ignore the error and proceed like normal.

But if you've gone through all these troubleshooting steps and there is still an error, understand that the site may have a serious security problem, and you should exercise extreme caution. If the site isn't one you have to visit, don't go there for a while. The admins may need time to sort out any serious issues.

Causes of the Connection Not being Secure

Browsers will return a "not secure" error when they can't verify awebsite's SSL certificate. SSL is a secure data encryption method that keeps transmitted data private and safe. If a browser detects a problem with a site's SSL certificate, it will stop the site from loading and display a message about it not being secure.

Many things can cause these errors, some of which are problems on the site's end. The website could have an expired SSL certificate, no SSL certificate, or one that wasn't set up correctly. It's also possible that a trusted organization didn't issue the certificate.

When this warning is seen in Chrome, you'll see Not secure next to the URL. Firefox displays a red line through a lock icon. Similar warnings can be seen in other browsers.
