Unable to register device: unknown server response error when registering device using Azure Functions
We currently make use of the IoT Central device bridge solution detailed in https://video2.skills-academy.com/en-us/azure/iot-central/core/howto-build-iotc-device-bridge to connect devices to IoT Central.
Within the Azure Function App we have multiple Functions running for different data processing requirements, depending on the device, before entering the telemetry into IoT Central. A single device's telemetry usually gets transferred to IoT Central on a 15 min interval.
This has been working well enough, though recently we have been occasionally receiving an 'Unable to register device: unknown server response' error while the Function registers the device with the IoT Central's DPS. I cannot find a clear reason as to why this would only sometimes happen and not on every attempt.
I also have not been able to find possible reasons for this specific error from the DPS.
Does anyone know what my issue could be? Any assistance would be appreciated.
