Azure integration getaddrinfo ENOTFOUND

Cloud Integrations
1

I have followed the tutorial here:

When i update the firmware with

// Get some data
  String data = String(10);
  // Trigger the integration
  Particle.publish("JB_Test", data, PRIVATE);
  // Wait 60 seconds
  Serial.println("Sent Test Data");
  delay(60000);

The code flashes fine and i can see it running, then i check the integration log and i can see i am getting the below error:
getaddrinfo ENOTFOUND myhubname.azure-devices.net

I can’t find any information on how to resolve this anywhere online. Any ideas?

Have you made sure the azure endpoint is actually reachable at that domain like outlined here?
https://docs.particle.io/tutorials/integrations/azure-iot-hub/#confirming-the-data-reaches-azure-iot-hub

That error indicates that the domain is not reachable.

Just tried running the command and found that i needed to add -d before the particle device id, but it seemed to run but gave me a long error, the summary is below:
[0] create a generic issue.

I’ve also just tried running:

az iot hub monitor-events -n {iothub_name}

Using the hub name and it gives me

Unable to find IoT Hub: MY-HUB-NAME in current subscription MYSUBSCRIPTIONNO.

After a lot of digging i’ve discovered that the IoT hub i created through the dashboard was not showing when i ran

az iot hub list -o table

I then used the CLI to create a new hub and this worked first time. Microsoft support were unable to tell me why the dashboard created iot hub wouldn’t show up.
