 # Troubleshooting with Azure IoT Hub Device Provisioning Service
 
-Connectivity issues for IoT devices can be difficult to troubleshoot because there are many possible points of failures such as attestation failures, registration failures etc. This article provides guidance on how to detect and troubleshoot device connectivity issues via Azure Monitor. To learn more about using Azure Monitor with DPS, see [Monitor Device Provisioning Service](monitor-iot-dps.md).
