Bluemix IoT Foundation Starter give Error: Lost connection to server
Bluemix IoT Foundation Starter give Error: Lost connection to server
我正在 Bluemix 中尝试 Internet of Things Foundation Starter 样板。以下是我要执行的步骤：
- 使用样板文件创建新应用程序
- 应用程序启动后，我转到 URL 并查看 NodeRED 主页
- 我单击按钮将我带到 NodeRED 编辑器
- 在另一个浏览器中 window 我在此处提供了物联网传感器：https://quickstart.internetofthings.ibmcloud.com/iotsensor/ up 和 运行
- 我用我的 IoT 传感器的地址配置 "IoT App In Node"。我删除了“：”并将字母变为小写。
- 当我在 NodeRED 编辑器中单击“部署”时，我看到以下错误："Error: Lost connection to server"
在第 2 步之后，我已经在日志中看到这些错误：

现在，如果我重新启动应用程序，一切正常。但我每次都可以通过以下步骤一致地重新创建上述场景：
- 从样板创建新应用程序
- 转到 NodeRED 编辑器
- 节点内配置物联网
- 部署
- 获取错误
- 停止和启动运行时
- 所有作品
需要帮助找出发生这种情况的原因以及如何预防。
