Open Website in the Different browser
After following the above workaround, the site still showing the “This Site is Not Secure” or “Security Certificate is Not Secure,” then maybe the problem is with your default browser. To troubleshoot this, you can try to visit the same website on a different site and check if this fixes the issue.
If the same website is working fine in another browser, then it is time to reset your browser to default settings.
Note: Following workaround will only work if you see certificate error because of your web browser.
What is Recommended?
If you highly trust the website you’re visiting; then you can ignore the warning message and visit the website. Also, if you have even a little doubt about if the site is genuine or not, I recommend not to visit the website.
In case, the website trusted by your regularly showing you the same certificate message back to back, then it is a good idea to drop a note to the administrator of the website. In the message, you can explain the whole issue with a screenshot so that admin can resolve the issue.
