 Cause:

While troubleshooting, found that the VM's Network Adapter showing configuration error as show below. This can happen if VM is connected to virtual switch that has been deleted.

Resolution:

1 Ensure that all VM's doesn't shows Configuration Error in hyper v server.

2 To fix the Configuration Error, either the NIC has to be connected to proper virtual switch or  Not connected.

3 Once the VM NIC status is corrected

4 Open an elevated Command Prompt window. To do this, click Start, type cmd, right-click cmd.exe in the results list, and then click Run as administrator.

3 At the command prompt, run the following command:

   net stop DRA

   net start DRA

4 On the Servers page in the Azure portal, Refresh the hyper v server.

 

After you complete these steps, you should be able to create a protection group successfully.
