Reactjs 为什么AWS PVCs中的Nginx config指向我的本地主机而不是AWS PVCs中的本地主机？

我使用Centos7在AWS PVCs中托管ReactJS应用程序和ExpressJS，并使用Nginx为ReactJS构建文件提供服务

• ExpressJS的应用程序正在端口5000上运行
• ReactJS的应用程序正在端口80上运行

下面是我的配置

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location /api/ {
                proxy_set_header        X-Real-IP               $remote_addr;
                proxy_set_header        X-Forwarded-For         $proxy_add_x_forwarded_for;
                proxy_set_header        X-NginX-Proxy           true;
                proxy_pass              http://localhost:5000;
                proxy_set_header        Host                    $http_host;
                proxy_cache_bypass      $http_upgrade;
                proxy_redirect          off;
        }

        error_page 404 /404.html;
                location = /404.html {
        }

        error_page 500 502 503 504 /50x.html;
                location = /50x.html {
        }
    }

}

当我试图访问端口80上的ReactJS应用程序时，它总是被请求到本地主机

如果我关闭笔记本电脑上的本地服务器，我会收到一条错误消息说CORS失败。

如果我打开笔记本电脑上的本地服务器，ReactJS应用程序将成功加载。

我是否遗漏了Nginx配置中的某些内容？因此它从未在AWS PVCs服务器中读取本地主机？
