Nginx downloads a file instead of going to index once you go to a folder url

I’m trying to setup phpmyadmin on my new ubuntu server running nginx. When I do domain.com/phpmyadmin/ it downloads a file consisting of php code etc while if I do domain.com/phpmyadmin/index.php it loads in correct. Got no idea why. This is my server block:

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

    root /var/www/domain.com/html;
    index index.php index.html index.htm index.nginx-debian.html;

    server_name domain.com;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }

    location / {
        try_files $uri/ $uri =404;
    }
}

and I have set ‘’‘cgi.fix_pathinfo=0’‘’.
