We often find these errors – “There is a problem with this website’s security certificate“, “Your connection is not private“, “The site’s security certificate is not trusted or “Can’t verify the identity of the website. The certificate for this website is invalid” while browsing the internet. This generally happens when you try to access an SSL certified website and your browser cannot establish a secure connection. The SSL is the Acronym for Secured Socket Layer. It protects user data like passwords and other confidential information in banking, social, and mailing websites.

There are 6 possible reasons for this kind of errors to occur. These are expired certificates, wrong host, self-signed certificates, untrusted root certificates, SSL certificate revocation or pinning SSL certificates. We’ll now discuss some actively used methods to fix the problem related to the website’s security certificate.

Ways To Fix The Site Security Certificate Error

We will discuss each and every possible way to resolve the issues relating to SSL connection errors.

1. Date And Time

This is one of the most common reasons why we have the SSL connection error. Windows OS sometime operate at a wrong Date and Time and we don’t care to fix it. Suppose you are browsing an SSL secured website in 2019 while the date mentioned in your computer is 2001. Henceforth the browser cannot validate the website’s certificates and thus you get errors like this. To avoid this kind of problems always make sure to keep your time and date in check.

2. Antivirus

Some time antivirus can block different applications or SSL Certificates from starting. This could be annoying but the Antivirus application does this on purpose to protect your computer. To use the certain site, you can turn off your antivirus temporarily to access it.

3. Invalid Cache And Cookies

Sometimes cache and cookies can also create problems related to SSL connections in the web browser. Thus it is better to delete your cache and cookies from the browser after you’re done with the work. Deleting them won’t delete your saved passwords and account information.

To delete cache, open your browser and press ctrl+shift+ del from your keyboard. It will redirect you to the browsing history window. You can exclude your browsing history if you would like and press Clear browsing data, it will clear all cache data from chrome and could protect you from such errors.

4. Firewall

In some cases, the Firewall of your OS rejects and block certain request from a website with invalid SSL. For the best possible reasons, you should avoid accessing such websites. But if it is really necessary you can momentarily turn the firewall off to check it. Make sure to turn on the firewall once you’re done with the site. Here’s how you can do that.

Step 1. Launch Control Panel and navigate to System and Security.control panel

Another Method

If the site’s SSL certificate has expired or is no longer valid then you can physically manipulate the URL to overcome SSL error. By removing the “s” from the “https://” you generally break the secured link between browser and server and it works by opening the HTTP version provided the website doesn’t have a redirect to HTTPS version.

But be careful not to provide any important information like bank accounts, debit/credit card numbers when using the non-secured site as it might not be safe.

Now you can browse for the SSL sites without the interruption of security certificate error. But there is one simple exception, in some cases, the owner does not renew the certificates of the websites. Therefore we cannot do much in this scenario apart from using the HTTP version(if redirect to HTTPS is not in place). A browser cannot access a website with an expired certificate and thus all we can do is click the Back to Safety button and ensure safe browsing.

Otherwise, these processes are very simple and will work efficiently to fix your certificate errors for all browser in all platforms like Windows, Android, etc.  I hope this article helped you to overcome the problem.
