Nginx
為什麼是我的上游本地主機？在 Nginx 中獲得 500 但沒有應用程序錯誤。“連接到上游時沒有實時上游”
我正在按照本教程使用 Nginx 在 CentOS 上託管一個 React 應用程序。該網站在我執行時有效（200 響應）
curl localhost:3000，但是當我嘗試訪問他的anthurie.com時，我收到 500 錯誤，並且此錯誤在/var/log/nginx/error.log2021/10/17 17:56:16 [error] 5379#0: *5 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.1.1, server: anthurie.com, request: "GET / HTTP/1.1", upstream: "https://[::1]:3000/", host: "anthurie.com" 2021/10/17 17:56:16 [error] 5379#0: *5 SSL_do_handshake() failed (SSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol) while SSL handshaking to upstream, client: 192.168.1.1, server: anthurie.com, request: "GET / HTTP/1.1", upstream: "https://127.0.0.1:3000/", host: "anthurie.com" 2021/10/17 17:56:17 [error] 5379#0: *5 no live upstreams while connecting to upstream, client: 192.168.1.1, server: anthurie.com, request: "GET /favicon.ico HTTP/1.1", upstream: "https://localhost/favicon.ico", host: "anthurie.com", referrer: "https://anthurie.com/" 2021/10/17 18:01:01 [error] 5379#0: *9 no live upstreams while connecting to upstream, client: 192.168.1.1, server: anthurie.com, request: "GET / HTTP/1.1", upstream: "https://localhost/", host: "anthurie.com" 2021/10/17 18:01:02 [error] 5379#0: *9 no live upstreams while connecting to upstream, client: 192.168.1.1, server: anthurie.com, request: "GET /favicon.ico HTTP/1.1", upstream: "https://localhost/favicon.ico", host: "anthurie.com", referrer: "https://anthurie.com/"不知道為什麼
upstream: "https://localhost/"應用程序大部分時間都在localhost:3000/etc/systemd/system/anthurie.service

嘗試在這裡
https替換http：proxy_pass https://localhost:3000;並重新載入 nginx。你說這
curl localhost:3000行得通，並且省略 curl 的協議假設http://. 很可能，您的後端應用程序不支持 HTTPS（或至少在此埠不支持）。
