The HTTPS error is one that can occur for numerous browsers and prevents websites with SSL certificates from opening. And when HTTPS not working on Chrome, it could hamper your progress.

The HTTPS error message varies in alternative browsers. For example, the NET::ERR_CERT_AUTHORITY_INVALID and SSL Error Cannot connect to the real (website URL) HTTPS error message tabs open in Google Chrome.

Then you’ll also see a red line crossing out the HTTPS text in the website’s URL in Chrome. These are a few potential fixes for the HTTPS error more specifically for Chrome.

Why HTTPS sites are not opening in Chrome?

When HTTPS is not working in Chrome, it could be both a problem at your end or that of the website’s administrator. On your end, it could be a VPN, both as an extension or a program, that has modified the network settings.

Also, certain antivirus or firewall software are also known to label HTTPS links as suspicious and insecure. Besides, an outdated or corrupt DNS (Domain Name System) cache is just as likely to lead to HTTPS not working in Chrome.

Quick Tip:

This error only shows up particularly in Google Chrome so the easiest way to get over it is to change your browser. We recommend Opera and we have strong reasons to do so.

First of all, Opera is one of the few browsers that offer a native VPN. And it’s free to use for an unlimited time. This well-balanced browser guarantees to outspeed rival browsers and doesn’t have any interference with web-based apps.


Try a fast browser that doesn’t take up a lot of RAM and includes privacy and security options.

How to fix the HTTPS not secure message in Chrome?

Certain websites have a red padlock at the top-left corner in Chrome and throw the Not secure error message. If the website doesn’t employ HTTPS, the administrator hasn’t gotten the SSL certificate yet.

A quick fix would be to enter https in the URL instead of http since some websites offer support to both. Or, you could try using a different browser, in case it’s a problem with the current one that’s causing the error.

That’s all there’s to the HTTPS not working in Chrome issue, and by the time you reach this part, the problem would be long gone. These methods would also help fix the ERR_SSL_CLIENT_AUTH_SIGNATURE_FAILED error in Chrome on Windows 10.
