我正在跟进本教程使用 Nginx 在 CentOS 上托管 React 应用程序。当我运行 时，网站可以正常工作（200 个响应）curl localhost:3000，但是当我尝试他的anthurie.com我收到 500 错误，并且此错误/var/log/nginx/error.log

我不知道为什么upstream: "https://localhost/"大多数时候应用程序都处于localhost:3000

我正在此服务器上运行一个具有类似 nginx 配置的 Java 网站。应用程序运行正常，但我不知道为什么会出现 500 错误。

答案1
https尝试用这里替换http：
proxy_pass https://localhost:3000;
并重新加载 nginx。您说这curl localhost:3000有效，并且省略 curl 的协议假定http://。很可能您的后端应用程序不支持 HTTPS（或至少不支持此端口）。
