Error: The messaging entity <badconsumergroup> could not be found. Connector fails to consume ingress
If the Azure IoT Hub Connector fails to pass incoming messages to the ThingWorx Platform, check the Connector log file for the following message:
2019-08-05 14:04:27.631 ERROR host
AzureIot-867cbe8f-c71c-49e2-8b80-b59202b0e3a1:

java.util.concurrent.CompletionException:
com.microsoft.azure.eventhubs.IllegalEntityException:
The messaging entity
'iothub-ns-a-hub-1318295-fd49fd7cde:
eventhub:a-hub~8191|badconsumergroup'
could not be found.
If you specified the wrong consumer group in your AzureIotHub Thing, this message appears repeatedly in the Connector log. In addition, the Connector fails to consume any ingress.
If you do not specify a consumer group at all, the Connector uses the $Default consumer group. If a consumer group is specified, it must also have been created in Azure IoT, using the hub's Built-in endpoint configuration page. Microsoft Azure recommends creating and using a non-default consumer group. This is especially true if you have other applications consuming events.
If you make a change in the ThingWorx Azure IoT Hub configuration, restart the Connector for the change to take effect.
