Apparently I am doing something wrong still, because I have exhausted all methods I've found and I still get the:
I have gone into /etc/vmware/ssl and grabbed the .crt file and tried to import that into the Trusted Root Certificates for the "Computer Account" and I have also tried to export the certificate (.cer) from Chrome when going to my ESXi page. However, I still get the error.
My server's name is esxiserver.home and the certificate shows:
Issued to: esxiserver.home
Issued by: VMware installer
Valid from: 9/13/2017 to 3/14/2029
Any help appreciated. I can still get to the site if I proceed to the unsafe site, but I'd like to remedy this annoyance.
Not sure if you had a chance to look at this article which talks about the error you are seeing :
