Can't send email from gmail in codeigniter, SMTP Authentication error - codeigniter

Question

I'm trying to send an email in codeigniter, but something wrong and i dont know how to fix it.
It success when I send in localhost, but when I upload my app into host, it cant send. This is my code
$this->load->library('email');
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.gmail.com';
$config['smtp_port'] = '465';
$config['smtp_timeout'] = '7';
$config['smtp_user'] = 'username';
$config['smtp_pass'] = '****';
$config['charset'] = 'utf-8';
$config['newline'] = "\r\n";
$config['mailtype'] = 'html'; // or html
$config['validation'] = TRUE; // bool whether to validate email or not
$this->email->initialize($config);
$this->email->send();
echo $this->email->print_debugger();
And this is my error when I submit an email

Answer 1

See if your email account is not active with difinições security for external access, if you need to grant access to your site's SMTP server (your email address) so you can perform authentication.

To send smtp gmail autenticated with codeigniter
1 - Be sure if openssl in your php instalation is enabled.

$this->email->from('gmail.login#googlemail.com', 'Your Name');
$this->email->to('recipient#destination.tld');
$this->email->subject(' CodeIgniter Rocks Socks ');
