Merhaba arkadaşlar. kodumu aşşağıya bırakıyorum. sendsmsSOAP istek göndermiyor. firma ile görüştüm onlara istek hiç gelmediğini söylediler. Sorunum ne olabilir?
Plesk ve laravel kullanıyorum.

 $smsCode = rand(100000, 999999);
        $res = Helpers::sendsmsSOAP(Helpers::phoneNumber($phone), 'Gymflock, Doğrulama Kodu: ' . $smsCode, $request->ip(), $request->server('HTTP_USER_AGENT'), null, 1);
        
        return $res;

 public static function sendsmsSOAP($telefon, $message, $otp = 0)
    {
        try {
            // $telefon = trim(str_replace(' ', '', $telefon));
            $message = trim($message);
            $username = env('SOAPSMS_USERNAME', null);
            $password = env('SOAPSMS_PASSWORD', null);
            $usercode = env('SOAPSMS_USERCODE', null);
            $accountID = env('SOAPSMS_ACCOUNTID', null);
            $originator = env('SOAPSMS_ORIGINATOR', null);
            $url = "https://webservice.asistiletisim.com.tr/SmsProxy.asmx?WSDL";
