Ошибка Nginx: 502 Bad Gateway nginx/1.23.2 на Docker + Django + Postgres

Вот ошибка, которую я получил из моего журнала

2022/11/15 04:30:08 [error] 29#29: *2 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.80.1, server: mysite.local, request: "GET /favicon.ico HTTP/1.1", upstream: "uwsgi://192.168.80.3:3000", host: "mysite.local", referrer: "http://mysite.local/"

И я не могу понять, в чем проблема. Мне удается запустить Docker и запустить nginx, postgres и django.

Это мой mysite.local файл. Я практикуюсь/обучаюсь.

server {
        listen 80;

        server_name mysite.local;

        root /app/mysite_proj;
        index index.php;

        # https://www.if-not-true-then-false.com/2011/nginx-and-php-fpm-configuration-and-optimizing-tips-and-tricks/

        # Deny access to hidden files
        location ~ /\. {
            access_log off;
            log_not_found off;
            deny all;
        }

        # max upload size
        client_max_body_size 75M;   # adjust to taste

        # Django media
        location /media  {
        alias /app/mysite/media;  # your Django project's media files - amend as required
        }

        location /static {
        alias /app/mysite/static; # your Django project's static files - amend as required
        }

         # Finally, send all non-media requests to the Django server.
    location / {
        include /etc/nginx/uwsgi_params;
        uwsgi_pass django:3000;
    }

}

Мой docker-compose.yml:

version: '3.9'
services:

  django_api_backend:

      POSTGRES_USER: ${DB_USER}
      POSTGRES_PASSWORD: ${DB_PASSWORD}

  nginx:

    ports:

    depends_on:

  local_db:

    environment:
      POSTGRES_DB: ${DB_NAME}
      POSTGRES_USER: ${DB_USER}
      POSTGRES_PASSWORD: ${DB_PASSWORD}

Мой nginx.conf

worker_processes  4;

    worker_connections  1024;
}

http {
    include       mime.types;
    client_max_body_size 25M;

    sendfile        on;
    keepalive_timeout  65;
    gzip on;
    gzip_disable "msie6";
    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_buffers 16 8k;

    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    include /etc/nginx/vhosts/*;
}

Впервые пишу здесь, давно ищу/слушаю :) Я ценю любую помощь, спасибо.
