Doubt it, as if you were unable to connect to vCenter you'd not be doing any reconfigure tasks. I expect you'll see a nearby line that says this is expected as you've configured it by thumbprint match. Can you include a larger log selection? What lines can you find surrounding the pattern "Configuring VM"?
