jwt - 突然运行coral.cloudiot.core apperas时出错

问题描述

我正在使用coral.cloudiot.core类（安装说明）。这是paho-mqtt的高级 API 。

请在下面找到我的代码的简化版本：

with CloudIot("./cloud_config.ini", config_section='DEFAULT') as cloud:
    while True:

        """if a defined if clause evalutes to True, 
        the following method is executed."""

        cloud.publish_message(message)

一段时间后，会出现以下错误消息。

我不明白如何解决这个问题。我很感激任何提示。
