A Server error occurred.
 An error occurred while processing the authentication response from the vCenter Single Sign-On server. Details:
com.vmware.vim.vmomi.core.exception.CertificateValidationException: Server certificate chain not verified.
Currently I am using vcenter 6.0 version.
I connected yesterday and an error like the picture above occurred.
I've searched but can't find the same symptom as the details.
Is there any solution?
What were you ”connecting” to, and using what client? Please be as specific as possible.
Once you resolve this issue you should consider upgrading if you run anything like production workloads, since 6.0 is no longer supported or updated.
