新的Nginx服务器块已成功解析，但无法访问站点

Question

我在sites-enabled和sites-available的名为“ findernext-ssl.conf”的文件中添加了以下服务器配置：

server {
        listen 443 ssl;
        listen [::]:443 ssl ;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;


        server_name findernext.inventivedesign.fr;



        # Redirect all non-SSL traffic to SSL.
        if ($ssl_protocol = "") {
                rewrite ^ https://$host$request_uri? permanent;
        }

        location / {
                proxy_pass http://127.0.0.1:8084/finder/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
                proxy_set_header Connection 'Upgrade';
                # timeout 43200000;
                # websocket_connect_timeout 43200000;
                proxy_connect_timeout 43200000;
                # so_keepalive on;
                tcp_nodelay on;
                # websocket_pass websockets;
                # websocket_buffer 1k;
         }
}

sudo nginx -t未显示任何解析错误。但是随后重新启动nginx之后，根本无法访问该站点。没有nginx错误，只是找不到。

我实际上只是克隆了另一个名为“ physio-ssl.conf”的文件，该文件有效，并且仅在不同的子域和重定向下看起来完全相同：

server {
        listen 443 ssl;
        listen [::]:443 ssl ;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;


        server_name physisolve.inventivedesign.fr;



        # Redirect all non-SSL traffic to SSL.
        if ($ssl_protocol = "") {
                rewrite ^ https://$host$request_uri? permanent;
        }

        location / {
                proxy_pass http://127.0.0.1:8084/physisolve/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
                proxy_set_header Connection 'Upgrade';
                # timeout 43200000;
                # websocket_connect_timeout 43200000;
                proxy_connect_timeout 43200000;
                # so_keepalive on;
                tcp_nodelay on;
                # websocket_pass websockets;
                # websocket_buffer 1k;
         }
}

这是怎么回事？谢谢。
