问Azure Sphere无法连接到边缘设备-- TLS握手失败

EN

我正在尝试以嵌套的方式将Azure设备配置为子设备，并将其设置为IoT边缘设备。以下是程序

1. 按照这个链接https://learn.microsoft.com/en-us/azure/iot-edge/tutorial-nested-iot-edge?view=iotedge-2020-11形成一个Azure IoT边缘设备的层次结构(顶层+低层1+低层2)，总共3层
2. 遵循https://learn.microsoft.com/en-us/azure-sphere/app-development/setup-iot-edge?tabs=cliv1将SPhere配置为顶层的子设备。
3. 我正在使用Azure示例，Azure IoT示例连接到边缘设备。对CMakeLists.txt和app_manifest.json文件(主机名为边缘设备的IP地址，证书为根证书(iotedge_config_cli_root.pem) )进行了必要的更改
4. 通过Azure门户，将Azure Sphere设备设置为边缘设备(顶层)的子级.
5. Azure Sphere设备是通过链接https://learn.microsoft.com/en-us/azure-sphere/app-development/setup-iot-hub?tabs=cliv2beta中的指令手动配置的
6. 按照步骤6，向IoT边缘设备提供Azure Sphere设备的租户CA证书，并将租户CA证书以PEM格式附加到iotedge_config_cli_root.pem。
7. 重新启动边缘设备，并尝试将球形设备连接到边缘设备。但没有成功。以下是edgeHub模块中的错误 <4> 2021-08-18 13:09:00.901 +00:00 [WRN] - TLS handshake failed., System.AggregateException: One or more errors occurred.

8. 在球面，下面是错误 IoT connection status: IOTHUB_CLIENT_CONNECTION_NO_NETWORK INFO: Azure IoT Hub connection started. INFO: Azure IoT Hub connection complete.

9. 根据https://github.com/Azure/azure-sphere-samples/blob/master/Samples/AzureIoT/Troubleshooting.md，在以下情况下可能会发生指向这些错误的错误：
10. 未在IoT边缘设备上打开入站端口8883。有关更多信息，请参见打开IoT边缘网关设备端口中的步骤3以进行通信。
11. 该示例使用的是不正确或无效的IoT边缘设备根CA证书。
12. edgeAgent和edgeHub模块不在IoT边缘设备上运行。

但理由1和理由3是可以排除的。入站端口8883在边缘设备上打开，所有边缘模块都在运行。

在解决这个问题时需要你的帮助。注意，球形设备能够直接连接到IoT集线器。
