Unable to retrieve IoT Edge modules information

Question

Hi Team, I am not able to see IoT edge modules in specific IoT Edge devices. But I can see IoT Edge information for other IoT hub devices where same access is given in the same location. Not able to get exact error. Compared networking rules, IAM and few other stuff. Everything looks fine but still get above error on particular devices. Please find below error screenshot.

Thank you in advance!

Hi @Khandu Shinde Thank you for posting the question here.

The error you are seeing implies that the IoT Edge device fails to establish connection with IoT Hub or send any communication about the modules. This likely could happen for one of the two possible reasons.

1. If the IoT Hub is behind a private end point and public access set to Disabled or not allowing the IP address of the client to access it, you will receive this type of error.
2. Your IoT Edge is working in a completely isolated network from the internet traffic.

You can check the public network access of IoT Hub from Azure portal Networking tab. Please refer to the below image for reference.

If public access is restricted to your IoT Hub, make sure your IoT Edge device is part of a VNet that accepts connections to the IoT Hub. Please refer to Ingress connectivity to IoT Hub using Azure Private Link for more information on this architecture.

Here is another resource that will walk you through the configuration steps needed to Using Azure Private Link and Private Endpoints to secure Azure IoT traffic

Hope this helps!
