It appears that as of today: 09-13-2019, the URL specified in:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Device Metadata\DeviceMetaDataServiceURL:

http://go.microsoft.com/fwlink/?LinkID=252669&clcid=0x409

is redirecting to a site that has a 'bad' certificate attached to it.

The above URL redirects to:

https://devicemetadataservice.trafficmanager.net/dms/metadata.svc



The certificate attached to this URL has name mismatch.

This seems (perhaps?) to be causing ALOT of issues/delays with device staging (Device Setup in Progress....for PnP devices)

Can anybody else confirm this and advise?

Attached is the Certificate warning, and then (upon continuing anyhow, the service is simply not available!):
