Invalid Grant

[Autoeurope Developer]

Hi All,

I have several scripts that run in cron jobs every day, (to update labels, download reports, set bidding options etc...). These have all been working fine for over a month, and today I started getting this message:

{ "error": "invalid_grant", "error_description": "Bad Request" } 

when trying to connect (with both my Test Account Token and my Main MCM Account token). I have Standard Access privileges, not sure if it's relevant.

Below is a simple script I use just to test the connection (which has also been working for over a month, until today). Nothing (really, not a single thing) has been changed on my side that could cause this error.

Any help is appreciated.

Thank you.

<?php
@session_start();
if(!isset($_SESSION['ae']['userId'])){
 echo 'Session has expired. please refresh your page and login again.';
 exit();
}
$t = microtime();
require_once '../_adwordsAPI/init.php';
if(isset($_POST['customerID'])){
 $cID = trim($_POST['customerID']);
}
try{
 $user = new AdWordsUser('../_adwordsAPI/auth.ini');
 $user->SetClientCustomerId($cID);
 GetAccountHierarchyExample($user);
 $ms = microtime() - $t;
 echo 'Connection Successful. Ping time = '.round(($ms*1000),3).'ms';
}catch(Exception $e){
  echo "An error has occurred: " . $e->getMessage();
}


function GetAccountHierarchyExample(AdWordsUser $user){
 $managedCustomerService = $user->GetService('ManagedCustomerService');
 $selector = new Selector();
 $selector->fields = array('CustomerId',  'Name');
 $graph = $managedCustomerService->get($selector);
 if(isset($graph->entries)){
 $cnt = 0;
 foreach ($graph->entries as $account) {
     $cnt ++;
 }
 echo 'This Account has <b>'. ($cnt -1) . '</b> Clients<br><br>';
  }else{
 echo "No accounts were found.<br>";
 }
}


exit();
?>
