CentOS 8 Nginx with PHP 7.4.8, PHP not excuted and give internal server Error

Iam new to CentOS, I installed LEMP stack with Virtualmin, and I have a wired problem that when I execute some PHP codes that use modules I added manually like Chilkat or ionecube loader the PHP gives internal server error 500 with an empty screen on the browser, but when I run this file using SSH command

php play.php

it executed correctly and show me the result on the screen so not sure what is the problem maybe NGINX and PHP-CGI? after I installed the LEMP stack manually I installed Virtualmin and there is my NGINX Conf file

server_names_hash_bucket_size 128;
server {
    server_name mydomain.com www.mydomain.com;
    listen ip;
    root /home/mydomain/public_html;
    index index.html index.htm index.php;
    access_log /var/log/virtualmin/mydomain.com_access_log;
    error_log /var/log/virtualmin/mydomain.com_error_log;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/php-nginx/159588147640444.sock/socket;
    }
    listen ip:443 default ssl;
    ssl_certificate /home/mydomain/ssl.cert;
    ssl_certificate_key /home/mydomain/ssl.key;
    fastcgi_read_timeout 60;
}

Thanks in advance.

I Solve the problem by using

fastcgi_pass unix:/run/php-fpm/www.sock;

instead of which is added when I setup Virtualmin with LEMP Stack.

fastcgi_pass unix:/var/php-nginx/159588147640444.sock/socket;

I don't know why it work and what is the difference between both of them, is the unix:/var/php-nginx/159588147640444.sock/socket; crashed or something?
and the old one works only with normal PHP pages but it can't execute modules or something like this it gives 500 Error.
the last thing I install LEMP stack first then I add Virtualmin with LEMP stack so maybe I installed 2 PHP version? not sure, I do this so I can use PHP 7.4.8 because Virtualmin LEMP stack comes with PHP 7.2
