You have a mistake in your $ipConfig, it should be the following:

$ipConfig = New-AzVmssIpConfig `
  -Name "myIPConfig" `
  -LoadBalancerInboundNatPoolsId $lb.InboundNatPools[0].id `
  -LoadBalancerBackendAddressPoolsId $lb.BackendAddressPools[0].Id `
  -SubnetId $vnet.Subnets[0].Id

so actually 2 mistakes :)

ps. figured that out with the following:

New-AzVMss -ResourceGroupName $rgname -VMScaleSetName VMSSKArt -VirtualMachineScaleSet $vmconfig -Debug
