PHP & SQL - A failed connection attempt - XAMPP

Question

Hey, guys, here’s my problem. I own my machine with a Mysql localhost, there is a website that I created, however, when I try to connect the DB of the site with another machine that is not connected to my WI-FI network or the error happens:

Warning: mysqli_connect(): (HY000/2002): An attempt to connect the failed because the connected component n answered correctly ap s a time per or the established connection failed because the host connected did not reply.

This error occurs only on external computers, even though everything works normal on my PC and others that are connected to my WI-FI network.

PHP connection of the site:

define('HOST', '192.168.1.244:3306');
define('USUARIO', 'monty');
define('SENHA', '[senha]');
define('DB', 'login');

$conexao = mysqli_connect(HOST, USUARIO, SENHA, DB) or die ('Não foi possivel conectar!');
mysqli_select_db($conexao, 'login') or die (mysql_error());

A few steps I’ve already taken:

=> Sql accounts have permissions to connect.

=> I already added the host account "%" for any ip.

=> Mysql’s my.ini bind address is IP 0.0.0.0

=> The IP I use in php connection is my ipv4.

=> I already allowed mysql and apache in the firewall, although it is turned off.

=> Apache and Mysql services are connected.

=> The login user of the php connection has global permissions.

=> I’ve already added the "Require all granted" lines to the httpd.xampp.conf file

Print of localhost accounts:

NOTE: All PHP code is being used in PHP Desktop and then converted into an executable by Inno Setup.

Anyway, thanks for your patience!
