Getting the Error "NSG 'xfusion-priv-nsg' does not allow access from the VNet's CIDR block '10.0.0.0/16'" for the Task 7 in Level 2 Cloud Azure practise

I am attempting Task 7 of Level 2 Cloud Azure. As per the task, I have created private Vnet, Subnet, NSG and VM. I also created Inbound Rule to allow access from Vnet within the range ‘10.0.0.0/16’. However, in the validation i am getting the error “NSG ‘xfusion-priv-nsg’ does not allow access from the VNet’s CIDR block ‘10.0.0.0/16’”. Unable to identify what is failing. Can I get help on this?
