Chrome “website connection not private”

You’ve probably encountered the error message “Your website connection isn’t private” while browsing the web, but what does this error actually mean? Read on to find out what’s causing this error and what you can do to prevent it in the future.

What does “not secure” mean in Chrome?

When you visit a website, your browser sends a request to the server on which the website is hosted. The browser then validates the installed certificate on that website to check current privacy and security standards. If the certificate is somehow not set up correctly, the website cannot be encrypted correctly. Instead of loading the website, the error message will be displayed.

Validating the certificate is ultimately a security issue Do you have more security questions or do you want to have your browser or WordPress website more secure? Take a look at our WordPress Security service.

Error message in web browsers

Each browser displays the error message differently. These variations therefore depend on the browser, but also on the operating system and the configuration of the certificate on the servers.

1. Google Chrome

The error appears titled “Your connection is not private,” and the subtitle contains the following message: “Attackers may try to steal your information through domein.nl (for example, passwords, messages, or credit cards)”.

This message is accompanied by an error code, which helps to find out the actual problem. The most common error codes is Google Chrome are codes like:

How to fix privacy error in Chrome?

Practice shows that privacy errors can arise on two different sides. On the one hand, we often see problems with the ‘client’, which in this case can be your browser, operating system or computer. On the other hand, we often see problems with the certificate on the website (wrong domain, expired or unsafe).

There are several actions you can perform to fix the privacy error. We will take you through the steps:

1. Reload the page

Close your browser and try loading the page again. It may be that something was not right in your browser or that the website owner reissues his SSL certificate.

2. Check your computer’s clock

If the time and date of your computer is not set correctly, you will also receive a privacy error message. So check whether the settings of your clock are correct with the local time.

If the time and date of your computer is not set correctly, you will also receive a privacy error message. So check whether the settings of your clock are correct with the local time.

It is possible to set the time automatically. You can do this in settings and date and time.

3. Clear browser cache and cookies

In case of privacy errors, it is always wise to clear your cache and cookies. If you do not want to lose this data, it is also an option to open the website in incognito mode. If the website then just works then the error can be caused by a Chrome extension that does not work properly. Disable it and try to load the website again.

Time required: 2 minutes.

  1. Open chrome’s settings menu.

    Click on the 3 points to the right of the address bar, so you can go to the settings.

    Google Aanvinken en wissen

  6. Click Clear Data

    Finally, you can click clear data and then you’re done.

4. Clear the SSL status on your computer

The browser caches SSL certificates to speed up subsequent connections. It is possible that the browser cache has stored an outdated version of the SSL certificate. That is why it is useful to clear the SSL status. Then try connecting to the website again.

5. Temporarily disable VPN or an antivirus

An antivirus or VPN can disrupt the connection to your website. By temporarily disabling you can try whether you now have access to the website. Of course, don’t forget to reactivate the antivirus later.

Of course, we hope that one of the above actions has fixed your privacy error message. If not, try updating your operating system to the most new version. Updating your system is important, check out our WordPress Update service for more information.

Finally, you can always try to restart your computer, and even your router. This can be annoying if you have a lot of tabs on, but restarting devices removes a lot of temporary cache and minor issues. So it can certainly also be a solution for the error message ”website connection not private”.
