“裸域”意外关闭了我电脑上的连接

Question

我在所有网络浏览器上都遇到了ERR_CONNECTION_CLOSED 我的计算机中我网站的裸域。除了我的电脑，我在任何其他设备上都没有发现这个问题。 www 版本也可以正常加载。

我已尝试清除过去 24 小时的浏览器历史记录，删除了缓存和 cookie。没有任何区别。

这是我的 nginx 配置。

upstream app_server {
  server unix:/run/gunicorn.sock fail_timeout=0;
}

server {
    server_name mydomain.com www.mydomain.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /assets/ {
        root /home/djangoadmin/v/myappname;
    }

    location /media/ {
        root /home/djangoadmin/myapp/myappname;
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;  # <-
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://app_server;
            break;
        }

    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}



server {
    if ($host = www.mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    if ($host = mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80 default_server;
    listen [::]:80 default_server;
    server_name mydomain.com www.mydomain.com;
    return 404; # managed by Certbot
}

这是设备问题还是与我的 nginx 配置相关的问题？如何解决这个问题？

Answer 1

终于明白了！原因是我的计算机的/etc/hosts 有一个指向127.0.0.1 的裸域条目。删除它解决了这个问题。
