phpmailer - phpemailer 提示Mailer Error: SMTP connect() failed

Question

今天遇到一个很诡异的现象,之前好好的phpmailer今天突然出bug了,提示Mailer Error: SMTP connect() failed,比较诡异的是,我在本地,不管是前端请求,还是命令行直接执行,都是正常的,然而在服务器上面,命令行执行可以正常发送,然而在前端请求的时候就出了问题,一直提示如上错误
phpmailer配置:

try {
        $mail = new PHPMailer();
        $mail->IsSMTP();
        $mail->Host = 'smtp.163.com';
        $mail->Port = 25;
        $mail->SMTPAuth = true;
        $mail->Username = 'xxx';//这里的信息隐去了,不是账户密码问题
        $mail->Password = "xxx";
        $mail->From = 'xxx';
        $mail->FromName = 'xxx';
        $mail->AddAddress($address);
        $mail->CharSet = "utf-8";
        $mail->Encoding = "base64";
        $mail->IsHTML(true);
        $mail->Subject = $title;
        $mail->Body = $body;
        return $mail->Send();
    } catch (phpmailerException $e) {
//        echo "邮件发送失败：" . $e->errorMessage();
        return false;
    }

前端控制器是用的最简单的代码测试的,引入helper 执行函数(CI框架)

$this->load->helper('email');
$res = Send('xxx' , 'aa' , 'bb');//xxx是需要发送的邮箱
var_dump($res);
