WPN_E_CHANNEL_CLOSED

WPN_E_CHANNEL_CLOSED is an HRESULT used by the Windows notification platform. It means that code tried to use a notification channel after the platform closed or revoked it.

What to check

Request a replacement channel through the supported API and send the new URI to the app service or backend.
Handle channel-expiry and channel-revocation notifications instead of retaining an old URI indefinitely.
Do not assume that a failed send proves the device is offline; the channel itself can be invalid.
