Решение 1:
Добавить следующие строки в ваш файл php

$mail->SMTPOptions = array(
	'ssl' => array(
	'verify_peer' => false,
	'verify_peer_name' => false,
	'allow_self_signed' => true
	)
	);

Часть кода для большей наглядности

$mail = new PHPMailer;
	$mail->IsSMTP();								
	$mail->Host = 'mail.company.com';		
	$mail->Port = '587';								
	$mail->SMTPAuth = true;							
	$mail->Username = '[email protected]';					
	$mail->Password = '6565dsgsdgsdggd654';

	$mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; 	

	$mail->SMTPSecure = 'tls';							
        $mail->setFrom('[email protected]'); 
        $mail->addAddress('[email protected]');    

	$mail->SMTPOptions = array(
	'ssl' => array(
	'verify_peer' => false,
	'verify_peer_name' => false,
	'allow_self_signed' => true
	)
	);

	//$mail->SMTPDebug = 4;
	$mail->CharSet = 'UTF-8';
        $mail->Encoding = '8bit';

Решение 2:
Смените хостинг или используйте чистый Linux, на Linux Server 20 все работает с дефолтными настройками

  • Нет соединения с сервером
    Некоторые особо интересные хостинги запрещают указывать хост в виде: «mail.company.com«
    Пример ошибки
2022-05-19 22:29:22 Connection: opening to mail.company.com:587, timeout=300, options=array ( 'ssl' => array ( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true, ),)
2022-05-19 22:29:22 Connection failed. Error #2: stream_socket_client(): unable to connect to mail.company.com:587 (Connection refused) [//volume1/web/mysite.space/PHPMailer/SMTP.php line 389]
2022-05-19 22:29:22 SMTP ERROR: Failed to connect to server: Connection refused (111)
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Решение:
Укажите значение Host как localhost

$mail = new PHPMailer;
	$mail->IsSMTP();								
	$mail->Host = 'localhost';		
	$mail->Port = '587';								
	$mail->SMTPAuth = true;							
	$mail->Username = '[email protected]';					
	$mail->Password = '6565dsgsdgsdggd654';
