Question

我在vmware上将azure IoT Edge设备设置为ubuntu linux VM。它已连接到我的IoT中心，没有任何问题。我正在尝试注册叶设备（raspberry pi-我已成功直接连接到IoT集线器-我已从集线器中删除了该设备）。 Edge设备被设置为透明网关。当我尝试通过Edge注册设备时，收到连接被拒绝的提示。设置了边缘设备上的iptables，以将MQTT转发到位于Azure-iot-edge docker网络上的edgeHub容器。这在python sdk的设备注册示例中。我得到的确切错误是

MQTTTransportStage: _on_mqtt_connection_failure called: Connection Refused: not authorised.
MQTTTransportStage(ConnectOperation): completing with error Connection Refused: not authorised.
SerializeConnectOpsStage(ConnectOperation): op failed.  Unblocking queue with error: Connection Refused: not authorised.
EnsureConnectionStage(MQTTSubscribeOperation): Connection failed.  Completing with failure because of connection failure: Connection Refused: not authorised.

MQTTTransportStage: _on_mqtt_disconnect called: The connection was refused.

MQTTTransportStage: disconnection was unexpected
This may cause the background thread to abort and may result in system instability.
Exception caught in background thread.  Unable to handle.
azure.iot.device.common.transport_exceptions.ConnectionFailedError: The connection was refused.

似乎转发没有发生。这是我的iptables

我的建议是，在IoT中心的“设备设置”中，确保IoTEdge设备与分支设备之间存在关联。 IoT Edge设备必须设置为叶设备的父级：

使用DeviceClient时，您的叶子设备必须指定GatewayHostName，并且必须是您的Edge设备（在IoT中心中设置为父设备）。没有这个，您将得到连接拒绝错误。

无法通过MQTT将分支设备连接到Azure Edge设备
