正在尝试部署我的第一个应用程序(后端)。 但是我遇到了 502 Bad Gateway 类型的错误。

我将 SparkJava 用于我的后端框架,它在端口 4567 上启动。 因此我扩展了 Nginx 的配置 (nginx/1.8.1)。但是问题一直存在。

server {
    listen 4567 default_server;
    listen [::]:4567 default_server ipv6only=on;
}

供参考:我的后端与数据库通信 (RDS aws amazon)

根据您的日志:upstream: "http://127.0.0.1:5000/" 我明白了,nginx 正在尝试连接到同一台机器上的 5000 端口,但它拒绝连接。 5000 端口上的 运行 是什么?您可能需要调查一下。
