laravel route not working on nginx ssl

I had configured lumen in 80 port, but when I configured 443 port for https, the routes could not working any more except index. And I created a test.php file in /public, I can visit it through https://site.com/test.php. Below is my site.conf file:

server {
    listen 80;
    listen 443 ssl;
    server_name site.com;

    if ($scheme = http) {
        return 301 https://$server_name$request_uri;
    }

    charset utf-8;
    root /var/www/html/site.com/public;
    index index.php index.html index.htm;

    ssl_certificate /etc/letsencrypt/live/site.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/site.com/privkey.pem;

    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets on;

    ssl_dhparam /etc/ssl/private/dhparam.pem;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128:AES256:AES:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK';
    ssl_prefer_server_ciphers on;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Are there something wrong?
