React-为什么我收到无限请求xhr sockjs-node

Question

我想使用Cpanel使我的网站在线。

但是成功上传它并可以访问网站后，我收到了一个无限请求XHR Sockjs节点。

  

Websocket'失败：WebSocket握手期间出错：意外   响应码：400

标题

如您所见，我在这里提出了要求：

  

sockjs-node / 901 / xxyjg0gp / xhr？t = 1550550901496

这只是几次：

  

sockjs-node / 901 / 0njhvqec / eventsource

我创建的网站是React-（Create-React-App）/ SPA /客户端渲染。

我的package.json：

我需要使用端口40000来通过端口80运行React.js，并且我已经使用Express.js进行后端操作，但是我不运行后端只是做出反应而仍然得到了它。
