When I try to add my ESXi hosts to the vCenter server I get the error "License file download from host.mydomain.com to vCenter Server failed due to exception: vim.fault.SSLVerifyFault.". I have SSL certificates from a MS CA installed on the vCenter Appliance 5.1 and the ESXi 5.1 hosts. I recently had to rebuild my vCenter server but previously it was working with these same certificates. Was there a trick to get the ESXi hosts to join that I have forgotten?
If I log onto the vCenter App. it looks like the root certificate is installed already. In /etc/ssl/certs it is already hashed and symlinked to VMware-SSO-SecurityTokenService-Root-CA.pem. Also I can't uncheck "vCenter Server requires verified host SSL certificates" because its greyed out.
