用于Wordpress的DigitalOcean Droplet上的Docker-Compose设置返回“拒绝连接”消息

如何解决用于Wordpress的DigitalOcean Droplet上的Docker-Compose设置返回“拒绝连接”消息

我正在努力处理我的docker设置（到目前为止，它是新的）。

我已经注册了一个域。域提供商指向DigitalOcean DNS服务器。

在我的DO Droplet上，我安装了Docker并设置了以下docker-compose配置：

version: '3'

services:
    db:
        image: mysql:8.0

        container_name: wordpress_db

        restart: unless-stopped

        env_file: .env

        environment:
            - MYSQL_DATABASE=wordpress

        volumes:
            - dbdata:/var/lib/mysql

        command: '--default-authentication-plugin=mysql_native_password'

        networks:
            - app-network

    wordpress:
        depends_on:
            - db
        
        image: wordpress:5.1.1-fpm-alpine
        container_name: wordpress
        restart: unless-stopped

        env_file: .env

        environment:
            - WORDPRESS_DB_HOST=db:3306
            - WORDPRESS_DB_USER=$MYSQL_USER
            - WORDPRESS_DB_PASSWORD=$MYSQL_PASSWORD
            - WORDPRESS_DB_NAME=wordpress

        volumes:
            - wordpress:/var/www/html
        networks:
            - app-network

    webserver:
        depends_on:
            - wordpress
        image: nginx:1.15.12-alpine
        container_name: webserver
        restart: unless-stopped

        ports:
            - "80:80"

        volumes:
            - wordpress:/var/www/html
            - ./nginx-conf:/etc/nginx/conf.d
            - certbot-etc:/etc/letsencrypt
        networks:
            - app-network
    
    certbot:
        depends_on:
            - webserver
        image: certbot/certbot
        container_name: certbot
        volumes:
            - certbot-etc:/etc/letsencrypt
            - wordpress:/var/www/html
        
        command: certonly --webroot --webroot-path=/var/www/html --email EMAIL --agree-to --no-eff-email --staging -d www.retronexus.net -d www.retronexus.de -d retronexus.net -d retronexus.de

volumes:
    certbot-etc:
    wordpress:
    dbdata:

networks:
    app-network:
        driver: bridge

我想在带有mysql和nginx服务器的docker上运行wordpress。我创建的NGINX配置是：

server {

    listen 80;
    listen [::]:80;

    server_name retronexus.net www.retronexus.net retronexus.de www.retronexus.de;
    
    index index.php index.html index.htm;

    root /var/www/html;

    location ~/.well-known/acme-challenge {
        allow all;
        root /var/www/html;
    }

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass wordpress:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $docuemnt_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    location ~/\.ht {
        deny all;
    }

    location = /favicon.ico {
        log_not_found off; access_log off;
    }

    location = /robots.txt {
        log_not_found off; access_log off; allow all;
    }

    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }
}

当我运行docker容器时，Web服务器和mysql工作正常。 Certbot引发错误，表明与域的连接已被拒绝。

我不确定这是否仍是由于传播引起的，但是当我对域执行ping操作时，我得到了肯定的答复。当我在浏览器中调用域时，什么都看不到。即使我希望看到wordpress设置屏幕。

我会错过任何事情吗？
