Follow these steps to diagnose why an HttpEndpoint stops receiving push messages from Simple Message Queue (formerly MNS)—starting with a local endpoint test, then checking the push logs from the online service.
Overview
This topic describes how to troubleshoot an HttpEndpoint that fails to receive messages in Simple Message Queue (formerly MNS).
Troubleshooting steps
Use the local debugging tool for topic HTTP endpoints to test whether the HttpEndpoint handles push requests correctly. This tool lets you validate authentication and message processing logic independently, confirming the endpoint is ready to receive messages before checking the online service.
If the local test passes but the endpoint still does not receive messages from the online service, check the push logs to identify delivery failures. For details, see Log Management.
