Webpack生产问题（ReactJs）

Question

我在webpack生产部署中遇到问题，我收到控制台错误，提示 net :: ERR_NAME_NOT_RESOLVED 。我认为我在某处缺少某些东西，但无法弄清楚。我已经尝试了几乎所有的Google搜索，但无法获得正确的提示。所以我不确定这是我的配置代码问题还是某些服务器端问题。 我已经在下面的package.json文件的脚本中附加了配置代码。我不知道我在哪里。

控制台错误： https://prnt.sc/o1giau

我在控制台中遇到以下错误

https://de-test.cc:65001/sockjs-node/info?t=1560479337759网：: ERR_NAME_NOT_RESOLVED

    };

此配置文件中的 devServer 是否需要？为什么我在控制台错误中看到 webpack-dev-server 。虽然我使用了生产模式，但这只是让我感到困惑，不是吗？还是我错过了什么？

如果任何人已经通过此类或类似的产品进行生产，那么任何帮助都是非常有意义的。谢谢！
