vCenter Server 8.x
There is a mismatch of thumbprint between the vmcam service and the machine SSL certificate
Step: 1
Validate the MachineSSL thumbprint by the below command.
# /usr/lib/vmware-vmafd/bin/
# openssl x509 -in /var/core/machine_ssl.cer -noout -fingerprint
SHA1 Fingerprint=XX:XX:XX:XX:XX:XX:
Step: 2
Make sure to have a snapshot of vCenter
Step: 3
Unregister vmcam by the below command
/usr/lib/vmware-vmcam/bin/
Step: 4
Re-register vmcam by the below command
/usr/lib/vmware-vmcam/bin/
Step: 5
Restart the vmcam service
service-control --restart vmcam
The above steps will update the vmcam cert thumbprint with the current Machine_SSL_Thumbprint
