Trying out using Windows Azure Notification Hubs in a Windows Phone 8.1 application.
When I call RegisterNativeAsync passing the httpChannelUri, it throws a RegistrationAuthorizationException:
HTTP
request failed.
HTTP Details:
Status: 401
Reason: Unauthorized
Full content: <Error><Code>401</Code><Detail>ExpiredToken: . TrackingId:eddc6885-7154-411d-8e5e-a4381a78e3f2_G17,TimeStamp:12/11/2014 1:50:48 PM</Detail></Error>
Why is this? I can't find any documentation explaining the reason.
