SMTP ERROR: Failed to connect to server: Connection refused (111) on Godaddy server

Question

I want to send mail using phpmailer. I have uploaded my phpmailer files on my Godaddy server. The below code is running in my localhost but not on my server.

2019-02-03 16:54:12 SMTP ERROR: Failed to connect to server: Connection refused (111)

The below is the code for php

<?php
include_once('PHPMailer/src/PHPMailer.php');
include_once('PHPMailer/src/SMTP.php');

$mail = new PHPMailer\PHPMailer\PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 0; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587,465
$mail->IsHTML(true);
$mail->Username = "mail@gmail.com";
$mail->Password = "password";
$mail->SetFrom("mail@gmail.com");
$mail->Subject = "Test mail";
$mail->Body = "Hello World";
$mail->AddAddress("mail@gmail.com");
if($mail->Send()) {
    echo "Message has been sent";
}
?>

Answer 1

use PHPMailer\PHPMailer\PHPMailer; <-- make sure these are not in a function
use PHPMailer\PHPMailer\Exception;

require 'path/src/Exception.php';
require 'path/src/PHPMailer.php';
require 'path/src/SMTP.php';

Use tls and not ssl it can be buggy

$mail->SMTPSecure = "tls";
$mail->Port = 587;
