Wierd problem

May 4 at 6:02 AM
Search is working and everyone has access

So I've downloaded this tool and tried running a query on my local Win10 machine towards the Search WebApp at http://search - the result are this: HTTP/1.1 403 FORBIDDEN
<?xml version="1.0" encoding="utf-8"?><m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><m:code>-2147024891, System.UnauthorizedAccessException</m:code><m:message xml:lang="en-US">Access denied. You do not have permission to perform this action or access this resource.</m:message></m:error>

If I change to http://portal and run the same query the result is this; HTTP/1.1 200 OK
Serialized Query:
What is "missing" on the Search WebApp ?
