I had redeployed my home lab vCenter appliance, and upon attempting to access the vCenter UI, I was denied access and encountered the following error “NET::ERR_CERT_INVALID“
Details in the Error
vc.virtuallywired.io normally uses encryption to protect your information. When Google Chrome tried to connect to vc.virtuallywired.io this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be vc.virtuallywired.io, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.
You cannot visit vc.virtuallywired.io at the moment because the website sent scrambled credentials that Google Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later.
I did a bit of digging around, and it seems to be a widespread issue with macOS Catalina and Google Chrome. Also, my previous vCenter installation had a signed certificate from ZeroSSL, which I believe is why I didn’t exhibit the issue before redeploying the appliance.
Fortunately, the fix was surprisingly easy. When you are on the error page, type the characters “thisisunsafe“, and you will be directed to the vCenter UI. The fix was permanent unless Google Chrome settings were reset.
If you would like to install a free SSL certificate for your vCenter, please check out this blog post, Replace Default vCenter Certificate with a Free Let’s Encrypt SSL
