Key notes
When you’re trying to access a website and Google Chrome says the certificate is not secure, but you know the certificate is valid, it’s warning you that the webpage you are on has a mixture of HTTP and HTTP resources.
Chances areyour connection is not securein Chrome. We’ve put together methods that will help you solve the problem.
A website certificate is vital. The website’s server uses the HTTPS certificate to prove the website’s identity to web browsers like Chrome.
This is crucial since anyone can create a certificate claiming to be valid. Chrome requires websites to use certificates from trusted organizations.
?️Quick Tip:
Before we begin troubleshooting and resolving the issue, we suggest that you view the required URL with a more trustworthy and end-to-end security browser.
It will tell you who issued the certificate, what sort of certificate it is, and whether the issuer is well-known and legitimate. You may set Opera One to notify you about public sites that use certificates issued by local vendors if you believe this might be the problem.

Why does Chrome say that the certificate is not secure?
The not secure warning you encounter on a webpage means the website does not provide an encrypted connection.
Here are some common Chrome errors you might encounter when using the web browser and what they mean.
Sometimes, third-party software on your PC is stopping Chrome from safely connecting to the web.
This error only occurs on Windows OS, and most likely, the culprit is the Superfish software on your computer.
You can remove it bydownloading the SuperFish removal tooland following the installation instructions.
What can I do when Chrome says the certificate is not secure?
1. Clear Chrome’s cache and cookies
Browsers store local copies on your computer data so that they don’t have to load the website from scratch every time you visit a website.
Clearing Chrome’s cache and cookies will help the website load from scratch with updated information and might help validate the website’s security certificate.
2. Flush your DNS records on Windows
Sometimes a DNS cache may become corrupted because of a technical glitch on the website’s administrative side.
It can also become corrupted because of DNS poisoning. DNS poisoning is when unauthorized domain names or IP addresses are inserted into the cache.
Flushing the DNS will clear any IP address or DNS records in your system’s cache. It helps to resolve connectivity and Internet security issues.
3. Use the Chrome DevTools
This usually happens when the website administrator hosts images on a secondary domain and that domain uses thehttp://connection.
However, Chrome will show you if the website has an expired, missing, or invalid SSL certificate. Click on view certificate, and you will find all the details regarding the website’s certificate.
How do I fix the site’s security certificate that is not trusted for Mac?
The certificate is the one MacOS uses to validate the connection you’re trying to make with the website’s server. macOS warns you if the certificate is invalid or has expired.
You can also clear your browser’s cache. Clearing the cache is important because the downloaded cache on your computer might be obsolete.
Another way you can troubleshoot this error is to ensure that the date and time on your device are in sync with the website’s server.
If you’ve tried the methods above but couldn’t resolve the issue, you can contact the website’s administrator for support.
For anyproblem with your website’s security certificate, we have prepared an in-depth guide to help you solve that. Speaking of which, we recently coverederror during SSL handshake with remote serverin a different guide, so don’t miss it.
