This can work because there are times when there could be some internet issue and even web browser malfunctioning due to temporary cache material. Once you are sure that it is not working, go ahead with the next solution.

2. Get Date & Time Correct

If the date and time of your computer are not correct, it can cause SSL certification validation error due to a mismatch of date and time. If your motherboard’s battery has become faulty, the date and time may not be updated. There are times when you could misconfigure the date and time. If you have selected a wrong local time zone, date and time can be different than the actual. Whatever the case may be, you should first check the date and time on your computer. If you are a Windows user, it is located at the bottom-right corner. If it is not accurate, here are the steps to follow. Step 1: Go to Start menu button. Search for “Date and time settings”. Step 2: Open Date and time settings. Toggle on “Set time automatically” if not already turned on. Step 3: If the date and time are not accurate, turn off “Set time automatically” and change the date and time manually.

3. Check SSL Certificate

We have already stated that the error could occur if the website’s SSL certificate might have expired. If your users are complaining that your website is not opening on the web browser, you can check the validity of your website’s SSL certification. If expired, you need to renew the certification. If you are using Chrome, right-click on the body and select “Inspect Element” option from the menu. You have to select “Security” tab and then click on “View Certificate” button.

If you find out that someone’s website’s SSL certificate has expired, you can report the website admin from their social media pages.

4. Do Not Use Public Wi-Fi

We all know that public Wi-Fi networks are never safe and secure. When you can try to open a website from an unsecured network, your browser will warn you. Therefore, if you are using public Wi-Fi network, you should change it to private or personal Wi-Fi network or even mobile data. You can also use mobile data hotspot as well. Similarly, if you have VPN turned on, you should turn it off and access the target website as usual.

5. Disable Browser Extensions

Some web browser extensions can malfunction and block websites from opening. They can trigger SSL certification related error messages. Therefore, it is wise to disable all the extensions on your web browser once and see if the problem is solved. If the problem stays, you can enable the extensions again. If the problem is solved, then you can disable extensions one by one and find out which one is causing the problem.  If you are using Google Chrome, type “chrome://extensions” on the address bar, and you will see all the installed extensions. Toggle them off at once and refresh the website that is not opening and showing error message.

6. Disable Your Antivirus

Antivirus could be a major reason why you are seeing the error. This is because most antivirus software offers online protection and when the website does not match its parameters, antivirus will block the website. Therefore, you have to either change the configurations and settings of your antivirus software or disable and uninstall antivirus software. If the problem is not solved, you can enable the antivirus software and try out other solutions.

7. Clear Browser Cache And Cookies

When you visit a website, your web browser saves certain data about the website so that you can open the website faster and in the same state as you left it the last time. These data are stored in the cache memory in the form of cookies. But sometimes, the old data can be the culprit behind the website not opening and showing the error message. Therefore, it is important that you clear the web browser data regarding the website to see if it fixes the problem. But before you do that, you should open the website in Incognito mode of the web browser. When you open the website in Incognito mode, the previously saved cookies in the cache memory will not work. If the website opens, then the issue is with the cookies and cache memory of the web browser. If you are using Chrome, click on three-dot icon at the top-right corner. From the menu, click on New Incognito Window option. If you want to delete cache memory and cookies, go to Settings from the menu. Go to Security and Privacy and click on Clear Browsing Data option. Thereafter, you should select “All Time” and finally, click on Clear Data button.

8. Clear SSL Cache

Apart from clearing your web browser cache and cookies, you can clear SSL cache on your system. SSL cache is where the website’s credentials are saved for faster loading. If you are using Windows operating system, go to Control Panel. Open Network and Internet option. Go to Content tab and click on Clear SSL State button. Once the clearing is done, click on OK button.

9. Reset Web Browser Settings

If clearing things are not working for you, you need to reset the settings of your web browser. When you reset the settings on your web browser, it can clear all the cache memory, cookies, browser history, customized settings, extensions, bookmarks and everything else. If you are using Google Chrome, go to Settings from the three-dot icon at the top-right corner. Once Settings window opens, search for reset. Click on Restore settings to their original defaults. Follow the on-screen to complete the process. Restart the web browser and see if the problem is solved.

10. Update Web Browser And Operating System

When the web browser you are using or the operating system of your device is not updated, there can be compatibility and security issues.
