預期用SOAPClient寫一支PHP去call WCF Service(只有WSHTTPBinding，沒有Basic)，以下程式是用來測試能否成功回傳結果，目前還無法成功，求解?

//$params的格式與代入的參數用WCFTestClient測試是有成功回傳值
try{       
    $params = array(
        'stringEncryptionAccount'=> $EncryptionAccount,
        'guidToken'=>$systoken,
        'stringErrorMsg' => $error
    );      
    echo "<pre>".print_r($params, true)."</pre>";
    $client = new SoapClient($url.'?wsdl',
        array(
            'trace'=>true,
            'exceptions' => true,
            'cache_wsdl' => 0,
            'soap_version' => 'SOAP_1_2',
            'encoding' => 'ISO-8859-1'
        )
    );  
    $OutParam = $client->GetDecryptAccount($params);
    $userid = $OutParam->GetDecryptAccountResult;
    echo 'Response'."<BR><BR>"; 
    echo 'userid: '.$userid."<BR><BR>"; 

} catch (SoapFault $e) {  
    echo '錯誤訊息: ' .$e->getMessage().'<br>';
    echo '錯行數: ' .$e->getLine().'<br>';
    echo '錯誤檔案: ' .$e->getFile().'<br>';
    echo '錯誤碼: ' .$e->getCode().'<br>';

die;
exit;
}

執行結果：

[更新]2021/9/16 於另一台Server測試相同程式，call相同的WCF service，同樣失敗，但錯誤訊息卻不同?
