PhpMailer error : Message could not be sent.Mailer Error: SMTP connect() failed

Question

I search google and this site and can't fix this phpMailer error and that's why I need you help.

I am sending email using following phpMailer code but all time it's showing me error message :

Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

PhpMailer Code

require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP();                                     
$mail->Host =  gethostbyname("smtp.gmail.com");  
$mail->SMTPAuth = true;                          
$mail->Username = 'hello@gmail.com';        
$mail->Password = 'password';                 
$mail->SMTPSecure = 'ssl';                       
$mail->Port = 465;                               
$mail->isHTML(true);   
$mail->Priority = 1; 

$to = 'to@gmail.com';
$mail->setFrom('support@site.com', 'Sitename');

// Send Email tto user ####################################
$mail->addAddress('some@gmail.com', 'Shibbir Ahmed');
// send email to admin #####################################
$mail->addReplyTo('some@gmail.com', 'Information');

$mail->Subject = 'Test Subject';

$get_templae = mysqli_query($conn, "SELECT * FROM email_template WHERE t_id = '8' ");
$get_restult =  mysqli_fetch_array($get_templae);
$template =  $get_restult['t_content'];

$mail->Body    = $template;

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

Can you please tell what I am doing wrong in this code ?

I am getting this error :

2016-04-21 15:19:51 SMTP ERROR: Failed to connect to server: Connection refused (111) 2016-04-21 15:19:51 SMTP connect() failed. github.com/PHPMailer/PHPMailer/wiki/Troubleshooting Message could not be sent.Mailer Error: SMTP connect() failed. github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Answer 1

Try to lower your gmail security, for the SMTP!

Link: https://www.google.com/settings/security/lesssecureapps

And add de debuginfo property to see more what is wrong.

$mail->SMTPDebug = 1;

you can change the value to 1 2 3 or 4 to ingress the filtering form debuginfo.

Hope this helps you out ;)

Answer 2

The best ways to debug PHPMailer errors is to uncomment

$mail->SMTPDebug = 3;

It will give you a detailed log of the events happening. From authentication all the way to where the request is successful or fails

Answer 3

Step1: Go to Gmail setting and enable IMAP. Step2: Clear your browser cache and check it.

If issue still persists lower your Gmail security by using "settings" tab. Gmail Security alert will be like this
