Laravel blank page in NGINX

I'm using NGINX as my web server. I added the following ngingx config in /etc/nginx/sites-enabled/default. I Also checked the addresses in my index.php. But I faced with a blank page. Please help me solve the problem.

server {
    listen 80;
    server_name my.site;
    root /var/www/html/myFolder/;
    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-Content-Type-Options "nosniff";
        index index.php index.html index.htm;
    charset utf-8;
    location / {
        try_files $uri $uri/ /index.php?$args;
    }
    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }
    error_page 404 /index.php;
    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }
    location ~ /\.(?!well-known).* {
        deny all;
    }
}

    listen myIP:443 ssl;
