I am trying to configure SMTP server using 'phpmailer' class, i am using my email account email and password from my '1and1' email server, this is the code i have tried but i am getting error of 'SMTP' connect() failed, i don't know what i am doing wrong.
code source: 'github'
<?php
require 'phpmailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.1and1.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'myemail#server.com'; // SMTP username
$mail->Password = '*********'; // SMTP password
$mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 993; // TCP port to connect to
$mail->setFrom('myemail#server.com', 'Mailer');
$mail->addAddress('receiver#gmail.com', 'Shaur'); // Add a recipient
//$mail->addAddress('shaurshori#gmail.com'); // Name is optional
//$mail->addReplyTo('shaurshori#gmail.com', 'Information');
//$mail->addCC('cc#example.com');
//$mail->addBCC('bcc#example.com');
//$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
//$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
?>

date_default_timezone_set('Etc/UTC');
require 'vendor/autoload.php';
$mail = new PHPMailer;
$mail->isSMTP();
//Enable SMTP debugging
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';
$mail->Host = 'smtp.mailgun.org';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "#email.com";
$mail->Password = "**************";
$mail->setFrom('emailTo','name' );
$mail->addAddress('emailFrom', 'name');
$mail->addAddress('');
$mail->Subject = 'Test';
$mail->msgHTML("<h1>Succes!</h1>");
$mail->AltBody = 'Succes';
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}

Change
$mail->SMTPSecure = 'ssl';
to
$mail->SMTPSecure = 'tls';
As it states on the 1and1 email outgoing server info "Outgoing port (TLS must be activated)"
