You may get the following error message on all the HTTPS sites you open in your browser:
In Google Chrome, you get:

Most of the times these errors are correct and you should not continue if you have to enter any sensitive information on the website. But sometimes this error becomes persistent and comes on all the HTTPS websites you open. This is due to many reasons. Let’s discuss the reasons and solutions one by one.
Date and time error
This is the most common cause of malfunctioning SSL certificates in browsers. You should make sure that the date and time of your computer is correctly configured. If your computer date has been reset to the default, you should configure it to the correct date and time. Close the browser and open again. This should fix your issue.
If you are getting these errors on a particular browser, it means that the configuration of that particular browser has been corrupted. You can reset the browser to its default configuration to resolve the certificate issue.
To reset the most common browsers, here are the guides:
If you are still getting the certificate errors, I would recommend uninstalling your web browser and clean installing it again. If you are getting errors on a specific website, you may want to read about installing a security certificate of a specific certificate provider here.
