Request params empty

[rmdhfz]

This my code :

public function LoginProxmox(){

		$proxmox = new Proxmox\Request;
		$configure = [
			'hostname'	=>	'192.168.*.*',
			'username'	=>	'******',
			'password'	=>	'******'
		];
		$login = $proxmox->Login($configure);
		print_r($login);
}

note: assuming my proxmox is on the local network
