IoT Hub connector with Thingworx-Exception while initializing stores, not starting partition manager

[Jareval2]

Hello, I'm working on a demo that connect an Azure IoT Hub with Thingworx using the connector, but I get two warnings and some erros at the begining of the execution of the azure-iot.bat file. I read that it could be something related to the Event-hub endpoint, but I think I have the azure-iot.conf file in order. The connection between the Azure IoT Hub and the Thingworx platform is stablished and I can import my IoT Device, but I believe those errors don't allow me to see the data I'm sending. Some help will be appreciated. Here are my azure-iot.conf and cxserver.log files:

try changing eventHubNamespace to this:

eventHubNamespace = "iothub-ns-kepservere-1413800-d6d1c2b2f1"

 Is the Azure connector running on the same machine or in the same network as the ThingWorx server? The ThingWorx server has a 10.x.x.x IP address which is not routable over the public internet

I also see the `hubname` and `hubHostName` have different capitalization. The Hub name in Azure must be all lower case letters and numbers only.

Can you post a screen shot of this part of your Azure account with part of any access keys hidden

Does the Policy key you are using have the correct permissions?

[Jareval2]

Hi, I verified and the policy key has all the permissions (registry read, registry write, service connect and device connect).

My IoT Hub name is "KEPServerEXHub", is that a problem? Because I can connect my KEPServerEX IoT Gateway and send data to the Hub without any problem using the hostname "KEPServerEXHub.azure-devices.net".

Here is my communication arquitecture: 

All is in the Azure Cloude, in the same Region and I can psping and ping my two Virtual Machines without any problem. Using their ip public address and their private address.

I tried tried to change the eventHubNamespace like you said but now i have this errors:

[Rick-Stanley]

The ConnectorVM on the ConnectorSubnet must be able to connect with the ThingWorx IP addresses on the ThingWorxSubnet.

Yes, due to a restriction in Azure blob naming the IoT Hub name must be all lowercase

Hello again, I already check that my ConnectorVM and ThingworxVm can communicate with each other. 

On the other hand, I followed what you said and created all over again my IoT Hub, all with lower case letters. And I'm getting the same error trying to connect.

I can import the device I have in the IoT Hub, but I can't see data comming to my Thingworx platform.
