Proxysql: ProxySQL 1.4.4 Unable to connect with laravel

[Aban]

Hi, we are facing some issues with the latest version of proxysql.
This is what we are using:

• PHP 5.4
• Laravel 5.1
• ProxySQL 1.4.4

We are getting a 'SQL STATE Connection refuse error'. I've checked the username and password and they are correct.
On december 14 we downloaded the source code and compiled ProxySQL and it worked fine, we did't have any issue with it, but now that we downloaded the oficial release of proxysql 1.4.4 our PHP + Laravel application is unable to connect to proxysql.

Also i am able to connect to proxysql using Sequel Pro with no issues.

What else can i give you to help you to fix this issue?

vim .config/database.php

add:

'options' => [
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
PDO::ATTR_EMULATE_PREPARES => true, //default is False
]

@wolfefu : thanks for jumping in.

@Aban : I never used Laravel, can you please provide your config file(s) (without password, if any)? I will plan to test Laravel

I tested again and i found that this only happen with the debug version of proxysql 1.4.4, the release version works fine.
I attached my proxysql.cnf.
