我有两种不同的服务：

• 帐户生成器：FastAPI应用程序
• 货币追踪器：分为Golang后端和React前端。

此外，我还设置了一个NGINX代理，以便管理所有请求。
我的docker-compose.yml

version: '3.9'

services:
  backend:
    container_name: myexample-backend
    build:
      context: backend
    command: ["air", "migrate", "&&", "air", "serve"]
    env_file:
      - backend/.env
    ports:
      - "18001:18001"
    volumes:
      - ./certbot/conf/:/etc/nginx/ssl/
    networks:
      myexample-webserver-network: {}

  frontend:
    container_name: myexample-frontend
    build:
      context: frontend
      dockerfile: Dockerfile
    env_file:
      - frontend/.env-prod
   command: ["npm", "run", "start:prod"]
    ports:

  webserver:

    image: nginx
    volumes:

    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - backend
      - frontend
      - myexampleapp
    networks:
      myexample-webserver-network: {}

networks:
  myexample-webserver-network:
    external: true

还有我的nginx.conf

server {
    listen 80;
    listen [::]:80;
    root /var/www/html;
    server_name myexampledomain.com www.myexampledomain.com;
    location /.well-known/acme-challenge/ {
        root /var/www/certbot;
    }

    location / {
        return 301 https://myexampledomain.com$request_uri;
   }
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    root /var/www/html;
    server_name myexampledomain.com www.myexampledomain.com;

    keepalive_timeout 65;
    proxy_connect_timeout 600;
    proxy_read_timeout 600;
    proxy_send_timeout 600;

    ssl_certificate /etc/nginx/ssl/live/myexampledomain.com/fullchain.pem;
    ssl_certificate_key /etc/nginx/ssl/live/myexampledomain.com/privkey.pem;

    location / {
        proxy_pass http://money-tracker:18010;
    }
}

server {
    listen 80;
    listen [::]:80;
    root /var/www/html;
    server_name money-tracker.myexampledomain.com www.money-tracker.myexampledomain.com;
    location /.well-known/acme-challenge/ {
        root /var/www/certbot;
    }

    location / {
        return 301 https://money-tracker.myexampledomain.com$request_uri;
    }

    location /api {
        return 301 https://money-tracker.myexampledomain.com/api$request_uri;
    }
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    root /var/www/html;
    server_name localhost money-tracker.myexampledomain.com www.money-tracker.myexampledomain.com;

   keepalive_timeout 65;
    proxy_connect_timeout 600;
    proxy_read_timeout 600;
    proxy_send_timeout 600;

    ssl_certificate /etc/nginx/ssl/live/money-tracker.myexampledomain.com/fullchain.pem;
    ssl_certificate_key /etc/nginx/ssl/live/money-tracker.myexampledomain.com/privkey.pem;

    location / {
        proxy_pass http://frontend:3000;
    }

    location /api {
        chunked_transfer_encoding off;
        proxy_pass http://backend:18001;
   }
}`

我在EC2示例中运行这些服务，购买了一个域，并在我的域提供商和Route 53中配置了所有必需的DNS记录。
我想在域（myexampledomain.com）上运行account-generator服务，在子域（www.example.com）上运行money-tracker服务money-tracker.myexampledomain.com。
到目前为止，这工作完美，但每当我试图从money-tracker前端www.example.com调用money-tracker.myexampledomain.commoney-tracker后端（money-tracker.myexampledomain.com/api），我得到一个502错误。此外，如果我试图从外部（Postman或Imnsomnia）到达，我也得到一个502错误。
有趣的是，容器是健康的，因为如果我ssh到EC2示例，我可以 curl 后端，它正在接收请求。
我尝试过编辑compose文件、NGINX conf文件、/etc/hosts文件等，但似乎都不起作用。
希望有人能帮助我。提前感谢。
