Bootstrap Error - Chef Client 15.4

I am trying to dabble me feet into CHEF world. Got a CHEF hosted trial account.

Trying to initiate a bootstrap of chef infra client 15.4.45 to a Win Server 2016 node from my Win 10 machine.

But getting Execution Expired Error. I have setup WinRM and also configured firewall along with HTTPS cert. I validated WinRM works as i can remote into host via it and run a simple ipconfig.
Not sure if I have a syntax error in the knife bootstrap command but any help would be appreciated. See attached screenshot
