+The correct version of `php-fpm` must be represented:
+```
+location ~ \.php$ {
+        include snippets/fastcgi-php.conf;
+#
+#       # With php-fpm (or other unix sockets):
+        fastcgi_pass unix:/run/php/[version].sock;
+#       # With php-cgi (or other tcp sockets):
+#       fastcgi_pass 127.0.0.1:9000;
+}
+```
+Where `[version]` is the correct version, EG: `php8.1-fpm`.
