Nginx 在某些块上拒绝连接，但在其他块上则不会

Question

我遇到了一个问题，我定义了几个服务器块来重定向流量。我的 nginx 配置如下：

server {

    listen 80;
    listen [::]:80;

    server_name deflector.io www.deflector.io;

    return 301 https://www.deflector.io$request_uri;

}

server {

    listen 443 ssl;
    listen [::]:443 ssl;

    server_name deflector.io;

    return 301 https://www.deflector.io$request_uri;

        ssl_certificate /etc/letsencrypt/live/deflector.io/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/deflector.io/privkey.pem; # managed by Certbot
}

server {

    listen 443 ssl;
    listen [::]:443 ssl;

    root /home/foundation/deflector/app/build;
    access_log /var/log/nginx/deflector/deflector.access.log;

    server_name www.deflector.io;

    location / {
        try_files $uri $uri.htm $uri.html /index.html;  
    }

        ssl_certificate /etc/letsencrypt/live/deflector.io/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/deflector.io/privkey.pem; # managed by Certbot
}

到 的流量http运行正常，并按预期重定向，但是到 的流量https://deflector.io被拒绝curl: (7) Failed to connect to deflector.io port 443: Connection refused。尽管最后一个块运行正常，但情况仍然如此。

我在这里有点想不出主意了，所以如果能提供任何帮助我都会很感激。
