WPN_E_CHANNEL_REQUEST_NOT_COMPLETE
WPN_E_CHANNEL_REQUEST_NOT_COMPLETE is an HRESULT used by the Windows notification platform. It means that the channel-creation request ended without returning a usable notification channel.
What to check for WPN_E_CHANNEL_REQUEST_NOT_COMPLETE
- Inspect the exception details and network state around the asynchronous channel request.
- Verify the packaged app identity and notification registration configuration before retrying.
- Use bounded retry with backoff instead of repeatedly starting channel requests in parallel.
Diagnostic interpretation
This result has the HRESULT value 0x803E0101. AllStat records the condition as “The notification channel request did not complete successfully.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the wpn / channel / request / complete operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
