When i test web page https://partner.microsoft.com/en-us/dashboard/Registration/Tenant/Hardware?step=GetStarted?step=GetStarted# - Reported error 404 Resource not found.

I found sample program HardwareApiCSharpSample on microsoft web pages. It was created only token with it and for create Product (for files hlkx submission) the same problem - Reported errr 404 Resource not found.

I dont known where is problem and what way send the hlkx files to certificate program portal. Can you help me.
