Azure IoT Hub Connector Error

Hello,

I have been trying to install the Azure IoT Hub Connector by following these instruction: PTC

I managed to get it to install the templates and shapes and then headed home for the day.

The next time I got to work I was not able to start the server..! It keeps giving me the following errors:

I tried doing it from a "fresh" computer to no avail, does anyone know what is the problem here ???

Re: Azure IoT Hub Connector Error

What's the URL to your ThingWorx instance?

Would you post the contents of your azure-iot.conf file, with keys deleted or obfuscated, please?

My hypothesis is that we need to look at the ThingWorx URL in your configuration file.

Re: Azure IoT Hub Connector Error

In your opinion, what could be wrong with the URL ? Unfortunately I cannot share it..

Appreciate your help Stephen.

Re: Azure IoT Hub Connector Error

I was going to provide some general advice about constructing web socket URLs, but this error jumped out at me:

13:51:51.398 [NettyClient-NIO-5] ERROR c.t.s.i.t.netty.NettyBytesChannel - Error while establishing

websocket connection on channel com.thingworx.sdk.impl.transport.netty.NettyBytesChannel$2@11b13f74.

java.net.ConnectException: Connection refused: no further information: localhost/127.0.0.1:8080

Your Azure IoT Hub Connector is making an attempt to connect to localhost. This can happen if the AZURE_IOT_OPTS environment variable is not set. When this happens, the Azure IoT Hub Connector uses default values, rather than the ones you specified in azure-iot.conf.

On Windows, you make AZURE_IOT_OPTS an environment variable, or SET it in your session. On Linux, you make it one of your exports. If I'm setting up a prod instance where things will be stable, I make it a permanent environment variable. On my local Windows machine, I create a cmd script that sets it right before running the hub:

set AZURE_IOT_OPTS=-Dconfig.file=C:\Thingworx-Azure-IoT-Hub-Connector-2.0.0.141\connector\conf\azure-iot.conf

  -Dlogback.configurationFile=C:\ThingWorx-Azure-IoT-Connector-2.0.0.141\connector\conf\logback.xml

azure-iot.bat

There's more information on setting the environment variable in ThingWorx Azure IoT Hub Connector Installation and Operations Guide v2.0. ​I hope this helps.
