Azure IoT Hub遗留WebJob连接报401未授权错误求助

问题现象 #

昨日起，用于读取Azure IoT Hub消息的遗留WebJob启动连接端点时抛出401错误：

Management operation failed. status-code: 401. status-description: Attempted to perform an unauthorized operation..

原有配置 #

此前使用默认eventHubName及iothubowner共享访问策略连接字符串：

HostName={our hoist here};SharedAccessKeyName=iothubowner;SharedAccessKey={key here}

该配置此前运行正常，昨日午间突发报错。

排查操作 #

• 更换备用连接字符串无效
• 检查iothubowner权限无异常
• 改用内置端点中的Event Hub-compatible endpoint后恢复正常

使用的已弃用NuGet包 #

• Microsoft.Azure.WebJobs 2.1.0
• Microsoft.Azure.WebJobs.ServiceBus 2.1.0
• WindowsAzure.ServiceBus 6.2.2
• WindowsAzure.Storage 8.7.0
• Microsoft.Azure.ServiceBus.EventProcessorHost 3.1.5
