Unable to provision IoT Edge devices on Linux using symmetric key

Th.L.H 1

I am doing the following tutorial to create and provision an IoT Edge device (on Ubuntu Server 18.04):
https://learn.microsoft.com/en-us/azure/iot-edge/how-to-provision-devices-at-scale-linux-symmetric?view=iotedge-2020-11&tabs=individual-enrollment

This is a part of another tutorial for deployment of Azure IoT Central gateway module: https://github.com/iot-for-all/iotc-ava-gateway/blob/main/README.md#provision-the-iot-edge-device-with-its-cloud-identity

However, I am unable to provision the edge gateway in my IoT Central.

The status of the IoT Edge service (sudo iotedge system status) is as follows:

And the service logs (sudo iotedge system logs) is as follows:

Any help or suggestions would be greatly appreciated!

Hello @Th.L.H ,

installation seems ok. I'm not sure about the connection to the IoT Hub.

Can you verify your device can access 4.4.4.4 or 8.8.8.8 to prove an internet connection could be possible?

Can you:

ping 4.4.4.4 ping 8.8.8.8

Also, check this troubleshooting page.

Hello @Th.L.H ,

so the device is capable to reach the internet.

You could also try to ping the IP address of your IoT Hub, just to make sure.

The reason for this issue is not clear yet, did you check the troubleshoot page too?
