在Cloud9.io上的Webpack开发服务器中运行我的React应用程序时，我收到“无效的主机标头”消息

我正在使用Cloud9.io ubuntu VM Online IDE作为环境，并且通过对该错误进行故障诊断而减少了使用Webpack开发服务器运行应用程序的速度。

我用以下命令启动它：

webpack-dev-server -d --watch --history-api-fallback --host $IP --port $PORT

$ IP是具有主机地址的变量，$ PORT具有端口号。

我被指示在Cloud 9中部署应用程序时使用这些var，因为它们具有默认的IP和PORT信息。

服务器启动并编译代码，没问题，虽然它没有显示索引文件。只有空白屏幕，“无效的主机头”为文本。

这是请求：

Webpack开发服务器由于我的主机设置而返回此消息。在webpack-dev-server / lib / Server.js第60行中。来自https://github.com/webpack/webpack-dev-server

我的问题是如何设置才能正确通过此检查。任何帮助将不胜感激。
