Unable to Power on VM in vCenter 6 - A general system error occurred: Connection refused

Today when i was trying to power on one of my VM in vSphere 6 Environment it's getting failed with message "A general system error occurred: Connection refused".

Then i tried to power on this VM by directly connecting with my ESXi Host from vSphere Client and i was able to power on my vm then question was why i cannot start the same VM if i am connected with my ESXi host through vCenter. Then i found a KB article from VMware on How to start/stop the services in vCenter Server Appliance Version 6.

VMware vCenter Workflow Manager Service was Stopped.
1. To get in to vCSA 6.0 Shell
    (a). I accessed my  vCSA 6.0 through Putty
    (b). Then to enable BASH access i executed this command
           shell.set --enabled True
    (c) Then to Launch BASH i executed this command

service-control --status vmware-vpx-workflow

Start the VMware vCenter Workflow Manager Service

service-control --start vmware-vpx-workflow

 After this i tried to Power On the VM again and i was able to power it on.
