111：弹性豆茎上的连接被拒绝

Question

我在我的电脑上用 JAVA Springboot 构建了一个 jar 文件并将其上传到 AWS elastic-beanstalk。 我可以在我的电脑上运行它，但是当我打开 beanstalk 的链接时它显示错误：

2020/08/26 06:40:20 [error] 3143#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 125.121.75.33, server: , request: "GET /favicon.ico HTTP/1.1", upstream: "http://127.0.0.1:5000/favicon.ico", host: "xxxxxx-env.eba-4gp64tmr.us-east-1.elasticbeanstalk.com", referrer: "http://xxxxx-env.eba-4gp64tmr.us-east-1.elasticbeanstalk.com/"

但是，网络日志看起来不错：

我在环境属性中将 SERVER_PORT 设置为 8080。

我应该如何处理这个错误？如果您需要任何其他信息，请告诉我。

感谢@Marcin 的提醒！ 我将 SERVER_PORT 设置为 5000 这个问题已经解决了！ 因为 Elastic Beanstalk 默认会监听 5000。
