I think that two things will help you in diagnosing such problems:
Use try-catch syntax. If something is wrong then you can catch this in block
use SMTP Debug for phpmailer
this is example how you can use mailer:
<?php
require('./vendor/autoload.php');
use PHPMailer\PHPMailer\PHPMailer;
class Mailer {
public $phpmailer;
public function __construct($addresses)
{
$this->phpmailer = new PHPMailer(true);
$this->phpmailer->SMTPDebug = 3; // here you can debug
$this->phpmailer->isSMTP();
$this->phpmailer->Host = 'SMTP.host.example.blabla';
$this->phpmailer->SMTPAuth = true;
$this->phpmailer->Port = 587;
$this->phpmailer->Username = 'username';
$this->phpmailer->Password = 'password';
$this->phpmailer->SetFrom('username', 'subject');
$this->phpmailer->CharSet = "UTF-8";
foreach ($addresses as $address) {
$this->phpmailer->AddAddress($address);
}
}
public function send($messageTemplate) {
try {
$this->phpmailer->MsgHTML($messageTemplate);
$this->phpmailer->Subject = 'subject';
$this->phpmailer->Send();
return true;
} catch (phpmailerException $e) {
echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
echo $e->getMessage(); //Boring error messages from anything else!
}
}
}
and use it:
$mail = new Mailer(array('test#test.com'));
if ($mail->send('some message')) {
echo "mail send";
}

A good idea is take test by parts, so:
First of all, ensure that there are no problems with sending emails, and then check your code!
1 - Can You send a e-mail using the web server (whitout use php)?
2 - Check if mail() function is enabled on your server, here's how to do it.
3 - After try run your code check the php logs in the server.
