I am not able to connect to the VM I created. It says there is an error in NetworkWatcherRG. I wish I could attach a screen shot here.
Network Watcher is not required for you to connect to a VM, so even if for some reasons you’re not able to deploy Network Watcher, it’s not a big deal for VM connection.
You might want to check:
Do you have any Network Security Group associated to the NIC of VM or Subnet where VM is located, or both? Do you have any rule defined that allows you to reach the VM?
Which error did you have when you failed to connect to the VM?
