NET::ERR_CERT_REVOKED driving you nuts after upgrading to OSX Catalina? Well it is driving me nuts for sure. I just found out that if you hit the NET::ERR_CERT_REVOKED error while accessing a page, in Chrome, you can simply continue clicking in the Chrome window and by typing the following: thisisunsafe. Of course you should only do this when you are sure you want to access the page as it basically is telling you that the certificate that doesn’t align with what Apple expects to receive. In my case, I use it for when I want to access our in-house developers cloud. Also, it appears that when you open the page in “developers mode” (go to More Tools >> Developer Tools” you can continue to the blocked page. Very useful to know!
It seems that deleting the cache helps out, too. At least here the message with a self singed vcenter certificate was gone after wiping the cache.
