PHPMailer_v5.1- SMTP Error: Could not authenticate - php

Question

I have the below code and I am getting the following error:
I am using the version PHPMailer_v5.1. I tried another version but it did not work. Any Ideas?
SMTP Error: Could not authenticate
$mail = new PHPMailer(false); // the true param means it will throw exceptions on errors, which we need to catch
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Mailer = "smtp";
$mail->SMTPSecure = "ssl";
$mail->Host = "smtp.easyname.eu"; // SMTP server
$mail->Port = 465;
$mail->SMTPDebug = 0; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Username = "info#mydomain.net"; // SMTP account username
$mail->Password = "*****"; // SMTP account password
$mail->AddReplyTo("$fromEmail", "$from");
$mail->AddAddress("$toEmail", "$toName");
$mail->SetFrom("$fromEmail", "$from");
$mail->Subject = "New enquiry to example (SUBJECT:'$subject')";
$mail->AltBody = "$message"; // optional - MsgHTML will create an alternate automatically
$mail->MsgHTML("$message");
$mail->Send();
if($settings['cc_sender'])
