        $mail->Host       = 'ssl://smtp.gmail.com';                    // Set the SMTP server to send through
        $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
        $mail->Username   = 'abc@gmail.com';                     // SMTP username
        $mail->Password   = 'xxxxx';                               // SMTP password

        $mail->Port       = 465;                                    // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above
    
        //Recipients
        $mail->setFrom('abc@gmail.com', 'Mailer');
        $mail->addAddress('receiver@gmail.com', 'Joe User');     // Add a recipient
    
        // Content
        $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';
    
        $mail->send();
        echo 'Message has been sent';
    } catch (Exception $e) {
        echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
    }
?>

Simple fix! $mail->Host is a web request not a socket and 465 is the wrong port! Try

$mail->Host = 'smtp.gmail.com'; 
$mail->Port = 587;
