(Get-AzureVNetSite).Name not returning VNet name

From @dwightsands via Twitter

Have a Connection on a VNET->VNET Gateway->Local Network Gateway. The Status field alternates from Succeeded to Not Connected

Hi. It's very strange, the Status is not connected then after 25 seconds switched to Succeeded for 2 seconds

This is a Site-to-Site connection

I can't get this to work because (Get-AzureVNetSite).Name is not returning my VNet name

specifying it manually doesnt work either

It ways the virtual network was not found but I can see it in Resource Manager

I think the problem is some of those diagnostic commands are for the classic portal

I believe I need to use Get-AzureRmVirtualNetwork

I did get that function to work but the diagnostics still cant find the vnet, says its not valid or could not be found

Does Start-AzureVNetGatewayDiagnostics work for Resource Manager?(Documentation sent: aka.ms/d1218828 &aka.ms/d1218828a)

Thanks,
