On the web, you’ll see two different types of URLs or links – one that starts with HTTP and the other that starts with HTTPS. HTTPS links use SSL certificates to make the connection secure or private. Sometimes users have reported this HTTPS sites will not open when using any web browser. For example, Google Chrome users can see their browser screen . Your connection is not private , NET :: ERR_CERT_AUTHORITY_INVALID error page.

NET :: ERR_CERT_AUTHORITY_INVALID
If you can’t open an HTTPS webpage with Google Chrome, Internet Explorer, Firefox, or any browser on your Windows computer, here are a few things to try.
HTTPS sites that do not open in any browser
You must take no further action unless or until you make sure that the problem is with you and not with the site owner. To do this, you need to open several websites that have HTTPS in the permanent link. If all HTTPS sites do not open in your normal browser – they open in other web browsers, it means that you need to resolve your issue.
1]Time of change
This is the most common solution if you cannot open HTTPS websites. By changing the date and time, you can resolve this issue in minutes. To change the date and time in Windows 10, open the Settings panel by pressing the Win + I button. Select Time and language > Date and time . Then click the drop-down menu Time zone and select a different time zone than the selected one. Now try to open any HTTPS site that displays an error.
2]Clear the SSL cache
Although it shouldn’t be a problem, sometimes this can create problems. You must clear the SSL cache. You can do this from the Internet Options> page Content tab . On that page, you will find an option called Delete the SSL status . Click on.
3]Check the SSL certificates
If you tried the above suggestions, but the problem persists, you may need to test the SSL certificate. To do this, go to this website and enter the full URL of the site that displays the privacy error. If it shows all the green ticks, it means that the SSL certificate of the site is in order and that only you encounter the problem. However, if you find a red cross, it means you can’t fix it, and the site administrator needs to take action.
4]Clear the DNS cache
Open a command prompt window and run the following command to clear the DNS cache:
Does that help?
I installed ProtonVPN, which seems to be a reliable VPN software for Windows. But I started getting this problem after installing the VPN. So if you’re using VPN software, turn it off and see if it helps.
6]Restart or reinstall the browser
If you’ve started receiving this privacy error message in Google Chrome, you can try resetting your browser first. Here are some links that can help you – Reset Chrome browser | Reset Internet Explorer | Reset Firefox. If this does not resolve the issue, you may need to reinstall your browser.
I hope something here helps you solve the problem.
