Chances are your connection is not secure in 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. Try the Opera browser as a fast workaround for more information about a site’s security certificate. 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 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.

This webpage has a redirect loop or ERR_TOO_MANY_REDIRECTS – The webpage you’re trying to access has too many redirects; probably because the cookies are not working correctly This webpage is not available or ERR_SSL_VERSION_OR_CIPHER_MISMATCH – The website you’re visiting has an outdated security code, and Chrome blocks the connection Connect to a network – You have to sign in before using your Wi-Fi portal and connect to the website ERR_SSL_WEAK_EPHEMERAL_DH_KEY – The website to which you’re trying to connect has an outdated security code Delete Expired DigiCert Certificate (Mac computers only) – The webpage uses a certificate that isn’t set upright on your computer This site can’t provide a secure connection; network error sent an invalid response or ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION – If the page had a problem which Chrome couldn’t understand, you’d see this error; the solution is to ‌contact the website owner

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 by downloading the SuperFish removal tool and 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.

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
