How to fix it : There is a problem with the security certificate on this website

When you browse the Web, your browser does a lot of things in the background to make sure that the Web sites you access are not exposing you to danger. Sure, your browser can do so many things to protect you, but it’s worth paying attention to the warnings it sends you.

One of the error messages you may encounter when using Internet Explorer is the warning “There is a problem with the security certificate for this site.” At first glance, this may seem alarming because the wording implies that your security has been compromised.

However, this error can also occur on sites that we know are 100% safe and secure. In many cases, these warnings are not caused by your computer or web browser at all. These certificates are used by websites to prove that they are who they say they are on the Internet. If your browser detects a problem with a certificate or even no certificate, it will issue a warning.

This guide will help you determine if the warning is caused by incorrect settings on your computer or web browser, or if the problem is related to the site itself.


What causes the “There is a problem with this site’s security certificate” error?

What causes the "There is a problem with this site's security certificate" error?

It turns out that the most common causes of such certificate errors are severely outdated date and time values. Although the error displayed by your browser varies, the solution is always the same: make sure the certificate is validated by updating the date and time on your system.

Remember that most security certificates do not work if the date and time are incorrect. It turns out that this particular problem may also be caused by PuP (Potentially Unwanted Program), called Browser Safeguard – there may be other similar programs causing this behavior.

Check your antivirus program

If you get the message There’s a problem with this site’s security certificate on your computer, your antivirus program may be the cause. In particular, it can sometimes interfere with your web browser and cause these and other error messages.

In most cases, however, the problem can easily be solved by changing your anti-virus settings. Sometimes one setting can affect the browser and cause this problem. If that doesn’t work, you can solve the problem by temporarily disabling the antivirus program.

If that doesn’t work, you may need to uninstall the software. After uninstalling, check to see if the problem persists. If not, consider switching to another program.

Check the time and date on your computer
  1. Click on the clock icon in the lower right corner and select Adjust Date and Time.

  4. When the problem is resolved, enable the Automatically set time option again.
