Paypal api – Paypal sandbox account response fails on server

I’m new to paypal and sandbox, however the algorithm works fine with my on the localhost,
whereas it fails to complete the transaction on remote, I’m using php laravel

the algorithm on my paypal controller :

 $request = new OrdersCreateRequest();
    $request->prefer('return=representation');
    $request->body = [
         "intent" => "CAPTURE",
         "purchase_units" => [[
             "reference_id" => rand(000000,999999),
             "amount" => [
                 "value" => number_format($amount, 2, '.', ''),
                 "currency_code" => AppModelsCurrency::findOrFail(get_setting('system_default_currency'))->code
             ]
         ]],
         "application_context" => [
              "cancel_url" => url('paypal/payment/cancel'),
              "return_url" => url('paypal/payment/done')
         ]
     ];

    try {
        //ddd($request);
        // Call API with your client and get a response for your call
        $response = $client->execute($request);
       // ddd($response);
   

        // If call returns body in response, you can get the deserialized version from the result attribute of the response
        return Redirect::to($response->result->links[1]->href);

    }catch (HttpException $ex) {

    }

When I dump the response it’s as :

PayPalHttpHttpResponse {#2005 ▼
+statusCode: 201
 +result: {#2012 ▼
 +"id": "29F719283B401012X"

      +"currency_code": "USD"
      +"value": "150.00"
    }
    +"payee": {#1975 ▼

    }
  }
]

    +"rel": "self"
    +"method": "GET"
  }
  1 => {#2017 ▼
    +"href": "https://www.sandbox.paypal.com/checkoutnow?token=29F719283B401012X"
    +"rel": "approve"
    +"method": "GET"
  }
  2 => {#2010 ▼
    +"href": "https://api.sandbox.paypal.com/v2/checkout/orders/29F719283B401012X"
    +"rel": "update"
    +"method": "PATCH"
  }
  3 => {#2009 ▼
    +"href": "https://api.sandbox.paypal.com/v2/checkout/orders/29F719283B401012X   /capture"
    +"rel": "capture"
    +"method": "POST"
    }
  ]
 }

}

and The Exception i get :

PayPalHttpHttpException
{"name":"UNPROCESSABLE_ENTITY","details":   [{"issue":"COMPLIANCE_VIOLATION","description":"Transaction cannot be processed due to a possible compliance violation. To get more information about the transaction, call Customer Support."}],"message":"The requested action could not be performed, semantically incorrect, or failed business validation.","debug_id":"a548bb80c1863","links":[{"href":"https://developer.paypal.com/docs/api/orders/v2/#error-COMPLIANCE_VIOLATION","rel":"information_link","method":"GET"}]}

I’ve tried multiple ways to resolve it like :
1- Changing the sandbox account region from EGY to US.
2- Changing the entire paypal account.

I would appreciate a little assistance here.
Thanks in advance.
