Awhile ago I posted a fix for the Chrome certificate issue on macOS, see below. I am posting a followup to this: https://itsjustbytes.com/2020/02/26/google-chrome-browser-certificate-issue/
In Big Sur Chrome seems to be even more finicky about this and one sure way to bypass it is to do the following, just remember make sure you trust the site! I found it mentioned here and this is the excerpt from this thread: https://stackoverflow.com/questions/58802767/no-proceed-anyway-option-on-neterr-cert-invalid-in-chrome-on-macos
There’s a secret passphrase built into the error page. Just make sure the page is selected (click anywhere on the screen), and just type thisisunsafe.

This worked perfectly when nothing else would. Short and sweet thanks for playing…
It’s Just Bytes...
