PhpMailer doesn't want to work?

Question

PHP

Guys, phpmailer doesn't want to work.
Here is my code

require_once __DIR__.'/class.phpmailer.php';

              $Mailer = new PHPMailer();
        $Mailer->SMTPDebug = 2;
        $Mailer->CharSet = 'UTF-8';
        $Mailer->IsSMTP();
        $Mailer->Host = 'smtp.yandex.ru';
        $Mailer->Port = 25;
        $Mailer->SMTPAuth = true;
              $Mailer->Username = "gorelov";
              $Mailer->Password = "pass";

      $Mailer->setFrom('gorelov', 'Mailer');
      $Mailer->addReplyTo('gorelov', 'Information');
      // $Mailer->addAddress('[email protected]');

      $Mailer->Subject = 'Here is the subject';
      $Mailer->Body    = 'This is the HTML message body <b>in bold!</b>';
      $status = $Mailer->Send();

In the logs it says:
You must provide at least one recipient email address - add at least one address for sending.
To do this, I "uncomment" the line // $Mailer->addAddress('[email protected]');
And nothing happens at all.
And I have a question:
1. What is wrong?
2. I uploaded only one class.phpmailer.php file to the server. Do you need any large files?

Answer 1

Yandex and other Googles have disabled non-ssl connections for a thousand years. not safe.

Answer 2

Try $Mailer->SMTPDebug = 3; and $Mailer->SMTPDebug = 4; More detailed debug modes. Maybe there will be an answer

Guys, forwarded the code with your clarifications, but nothing has changed(
And it does not show any additional errors. Changed the encryption type and port.
Zero emotions(

$Mailer = new PHPMailer();
        $Mailer->SMTPDebug = 2;
        $Mailer->SMTPDebug = 3;
        $Mailer->SMTPDebug = 4;
        $Mailer->CharSet = 'UTF-8';
        $Mailer->IsSMTP();
        $Mailer->Host = 'smtp.yandex.ru';
        $Mailer->Port = 465;
        $Mailer->SMTPSecure = 'tls';
        $Mailer->SMTPAuth = true;

Answer 4

$Mailer->SMTPSecure = 'tls';
