How To Fix Google Chrome SSL Warning

Starting from September 2021, all the devices using Windows 7 and older Windows OS versions started to give “Invalid SSL Certificate Warning” messages.

As as result, most of the commonly used websites (speedtest.net for instance) stopped opening properly or not loading at all.

After trying multiple solutions online, this one worked for me on multiple Windows 7 systems.

All you need to do is download and install all these SSL CA certificates and install them one by one:
https://secure.globalsign.net/cacert/Root-R1.crt
https://letsencrypt.org/certs/lets-encrypt-r3.pem
https://letsencrypt.org/certs/isrg-root-x2.pem
https://letsencrypt.org/certs/isrgrootx1.pem

Once you have installed all these certificates, just restart your browser and you are good to go.

Now you can test by opening any website that was previously throwing errors.

If you are having any issues, feel free to ask in comments and I’ll be glad to help.
