Question

由于未经授权的访问，我面临从IoT Edge设备到其IoT Hub的连接问题（显然）。在个人（常规路由器-ISP）网络连接下，该相同设置可以正常工作，但是一旦在更大，更安全的网络中进行设置，则该设置将失败。

我确保为设备的静态IP打开了所有必需的端口，并且连接字符串没有错字，但问题仍然存在。经过研究，我发现一些有类似问题的用户在SAS身份验证方面遇到了麻烦，尽管我从未更改过它，也没有在之前进行的任何测试中摸过它，所以我不妨使用它。我遇到的错误日志如下：

在最后一条警告消息之后，它会不断循环检查边缘运行时状态和连接失败，因此它从不下载模块，因此无法正常运行。该设备是运行树莓派的树莓派。

关于这个问题有什么想法吗？

谢谢！

发现了问题，如果有人遇到相同的问题，请在此处发布。

该设备无法自动获取日期和时间，因此该设备与Azure的日期和时间不匹配，从而导致了身份验证错误。

将树莓的日期和时间设置为我所在地区的当前日期和时间即可解决此问题。
