PHP webpage downloads instead of opens in browser (nginx, php on debian10 server)

I have a server running Debian 10. I have installed nginx (1.18.0) and php and php-fpm (7.4.28). Following this guide https://landchad.net/index I was able to get html website with certification by certbot running. Then I wanted to use php to have menu on my website dynamic. When I go to the webpage it downloads instead of opening up.

My file tree is as follows: my webpage is stored in /var/www/dragallur, there is a file phpinfo.php with the following code (if I type dragallur.xyz/phpinfo.php it asks me to download the webpage):

<?php phpinfo(); ?>

In the directory /etc/nginx/sites-available there are two files, default and mywebsite, default has following contents:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;

    index index.php index.html;

    server_name _;

    location / {
            try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    location ~ /.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;}}

And the file mywebsite:

server {
    server_name dragallur.xyz ;
    root /var/www/dragallur ;
    index index.php index.html index.htm index.nginx-debian.html ;
    location / {
            try_files $uri $uri/ =404 ;
            #try_files $uri $uri/ /index.php?q=$uri&$args;
    }
    
    location ~ /.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    }

listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/dragallur.xyz/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/dragallur.xyz/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 ($host = dragallur.xyz) {
    return 301 https://$host$request_uri;
} # managed by Certbot


    listen 80 ;
    listen [::]:80 ;
    server_name dragallur.xyz ;
return 404; # managed by Certbot}

This issue seems to happen quite often to people. I have tried cleaning my cache, I have done countless changes to the two files above but I still get the same problem. There may be other key config files so just tell me and I will share the contents. After every change which I think might be useful I run the command

systemctl restart nginx
