This issue can occur if the host certificate has one of these problems:
  • The host name does not match the Subject Name(s) in certificate.
  • vCenter Server is unable to recognize the local issuer certificate.


To resolve this issue, regenerate the ESXi host certificates.
To regenerate new self-signed certificates for ESXi, see the Generating New Self-Signed Certificates for ESXi section in the vSphere Security guide.
