Unable to connect from chef-client to chef-server using packer chef-client provisioner

i have been trying to install chef-client using packer in azure vm windows 2016 datacenter image but after creating image i checked in chef workstation that the image with chef-client configuration machine is not connected to chef server.

Is it necessary to perform knife command manually? but knife commands need private IP of vm so how can image with chef-client configuration will auto connect to the chef server?

Here is template code that i have tried:

{

"type": "chef-client",

"install_command": "powershell.exe -Command (New-Object System.Net.WebClient).DownloadFile('http://chef.io/chef/install.msi', 'C:\\Windows\\Temp\\chef.msi');Start-Process 'msiexec' -ArgumentList '/qb /i C:\\Windows\\Temp\\chef.msi' -NoNewWindow -Wait",

"Server_Url": "https://api.chef.io/organizations/xyz",

"Guest_Os_Type": "Windows",

"Chef_Environment": "",

"Ssl_Verify_Mode": "Verify_None",

"chef_license": "accept",

"Validation_Key_Path": "C:/packer/packer-repo/packer-master/DE/setup_files/xyz94.pem",

"Skip_Clean_Client": "True",

"Skip_Clean_Node": "False"

    

},
