Hi,

Please try to run the next:

C:\Program Files\VMware\vCenter Server\vmafdd\vecs-cli entry create --store TRUSTED_ROOTS --cert FULL_PATH_OF_CERT --key FULL_PATH_OF_KEY

For the path please use the same that is in your folder, what is going to do is adding this .cer in the TRUSTED_ROOT store. I do not think you will need to delete the old certificate but in case needed please take a Snapshot first and run:

C:\Program Files\VMware\vCenter Server\vmafdd\vecs-cli entry delete a727c0f89ce6a6c025da7fe4d80c1438c70e1aa7

That number is the ALIAS of your expired certificate with is showing error in the vCenter Inventory Service log.
