IoT Hub Connector setup throw Unable to connect to platform

Hi,

I have been following article https://community.ptc.com/t5/IoT-Tips/Connect-Azure-IoT-Devices-Part-1/ta-p/833021

As per article version of HubConnection Extension should be azure-iot-hub-adapter-extension-4.2.0.4 but I found for thingWorx 9.2 has version "Thingworx-Azure-IoT-Hub-Connector-4.3.0.3". 

I also notice that azure.iot.conf (below) has just 3 properties but article has 10. I dont know from where read value for "hub-thing-name". When I run "azure-iot.bat" I get "java.lang.RuntimeException: Unable to connect to platform" error.

Please help to point to most current article/lab or fix existing one.

protocol {
file-upload-events {
// Should the receiver for file-upload notifications be started?

// Name of the Thing (using template AzureStorageContainerFileRepository) which is associated to the storage container
// linked with this IoT Hub (within Azure Portal: Hub > File upload (under Messaging) > Storage container).

// This thing does not need to exist prior to starting the connector, but any file-upload events received
// before this Thing exists will fail and not be retried.
repository-thing-name = "<Your File Repsitory Thing Name Here>"
}

// This is the thing name that represents your Azure IoT Hub in Thingworx

}
