When I adding ESX server to vCenter in both 6.7 and 7.0 versions, I constantly get the following error, what can I do about it. I'm sure the DNS, IP, SM and NTP settings are all correct.
"The certificate on 1 host could not be verified. the sha1 thumbprints of the certificate is listed below. to continue connecting, manually verify this certificate and accept the thumbprint below."
You might want to reconfirm your IP address in the network between hosts that have been issued with certificates. I came across the same issue a few days ago where I had 1 IP address assigned to 2 hosts.
