111：彈性豆莖上的連接被拒絕

Question

我在我的電腦上用 JAVA Springboot 構建了一個 jar 文件並將其上傳到 AWS elastic-beanstalk。 我可以在我的電腦上運行它，但是當我打開 beanstalk 的鏈接時它顯示錯誤：

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，網絡日志看起來不錯：

我在環境屬性中將 SERVER_PORT 設置為 8080。

我應該如何處理這個錯誤？ 如果您需要任何其他信息，請告訴我。

Answer 1

謝謝@Marcin 的提醒！ 我將 SERVER_PORT 設置為 5000 這個問題已經解決了！ 因為 Elastic Beanstalk 默認會監聽 5000。
