As mentioned earlier, website security certificates are a crucial digital tool that helps a browser differentiate between a secure and an insecure website.

These certificates are downloaded by our browsers on the very first visit to the website,

That in turn helps a user in accessing the website in an easy and fast manner.

Further mentioning, these certificates are valid for only a limited period of time, otherwise SSL certificate may Expire.

i.e., 1 to 3 years. So, in order to maintain trust, an owner needs to renew them regularly. 

But sometimes our web browser misinterprets it,

Because of the incorrect date and time of our PC, and as a result, can show you this error.

Therefore, it is recommended to verify the date and time, and if it is a mess, then fix it by following these simple steps:

💻 For Windows:

  1. Right-click on the date and time.
  2. Select “Adjust Date/Time.”
  3. Turn on the “Set time automatically” and “Adjust for daylight saving time” options.

  10. After that, press “Save.”
  11. Lastly, select the correct “Time Zone” and done.

2. Clear History and Cache Data 🌀

If fixing the time and date has not helped you in any way, then you can try clearing your browsing history and cache data. 

To explain it simply, whenever we visit a website on our browser for the first time, it stores some part of its cache and history,

So that a user can easily access the website in the future.

Moreover, the stored cache makes it easy for the browser to load the website in a snappier way.

Although, many a time web browsers are unable to upgrade to the latest cache and history of the website,

Thus causing this error,

And this is why a user can try clearing the cache and history by navigating to the browser settings.

Want some assistance on this procedure? 

Then follow this tutorial that is mentioned below.

  1. Open your browser.
  2. Then, click on “Settings.”
  3. Now, click on “Privacy and Security.”
  4. After that, click on “Clear Browsing Data.”
  5. Then, navigate to the “Advanced” section.
  6. Next, click on “Clear data.”
  7. A confirmation window will pop up.
  8. Lastly, click on “Clear.”

3. Manually install missing certificates 🙌

Now, if clearing the history and cache part did not work for you (which happens rarely),

Then you can try adding website certificates to your browser manually.

But I should clearly warn you that adding the certificates of a strange and suspicious website may cause more harm than good.

Where to find SSL certificates? Let’s continue

So, if you are ready to take the blind fall, then you can proceed with the following steps:

  1. Type in the URL of the website, or do a quick Google search and access the website.
  2. Now, when the “Website not secure” message pops up, then click on the “Continue to this website” option, which is located at the bottom of the message.
  3. Click on “More Information” to access the “Certificate Error” option which is next to the red “Address Bar.”
  4. Then, click on “View Certificates” in the information window.
  5. After that, select “Install Certificates” and then follow the instructions accordingly.

4. Disable the certificate address mismatch option 𐄂

Lastly, you can try disabling the certificate address mismatch option.

Now, if you have no clue what is a “Certificate Address Mismatch” option, then let me explain.

A Certificate address mismatch is a built-in feature that blocks a website when there is a common mismatch in the URL of a website to which the SSL certificate is issued.  

For instance, if you are visiting instead of,

Then it can cause a mismatch and throw you this certificate mismatch error. 

So, to tackle it, you can try disabling the feature by following these steps:

  1. Go to the “Control Panel.”

  3. After that, click on the “Advanced tab” that is located at the top.

Tried everything that is mentioned above, but still no luck?

Well, I have to say this but you can’t do anything,

Because probably the problem is with the website itself. So, just wait for the owner to solve the issue.
