iot - 无法通过 MQTT 将叶设备连接到 Azure Edge 设备

问题描述

我有一个 azure IoT Edge 设备在 vmware 上设置为 ubuntu linux VM。它连接到我的物联网中心没有任何问题。我正在尝试注册一个叶设备（树莓派 - 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 设备设置为透明网关。当我尝试通过 Edge 注册设备时，连接被拒绝。边缘设备上的 iptables 设置为将 MQTT 转发到 azure-iot-edge docker 网络上的 edgeHub 容器。这是来自 python sdk 的设备注册示例。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.

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.

看来转发没有发生。这是我的 iptables
