Ionic / Leaflet - Can't get Tiles 404 Not Foun

Question

I'm locked with an issue that is very odd. I'm using leaflet with angular-leaflet-directive. On the previous app, everything worked.

Now on a new app, I'd like to implement a new leaflet map. I have therefore copied my previous code.

My Issue is that, the leaflet map opens, my markers are created, but

TILES are not loaded

(I do have internet & internet rights for my app) Every tile that tries to be loaded failed and gets the following issue :

GET http://a.tile.openstreetmap.org/18/98891/132985.png 404 (Not Found)

As you can see, if direct access to the tile, you can see it on browser.

Header of each Tile GET request

    GENERAL
      Request URL:http://a.tile.openstreetmap.org/18/98892/132984.png
      Request Method:GET
      **Status Code:404 Not Found (from cache)**
    RESPONSE HEADERS
      Client-Via:shouldInterceptRequest
    REQUEST HEADERS
      Provisional headers are shown
      Accept:image/webp,*/*;q=0.8
      User-Agent:Mozilla/5.0 (Linux; Android 5.0.1; GT-I9505 Build/LRX22C; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/42.0.2311.137 Mobile Safari/537.36

My feeling is that is it trying to load it from cache instead of directly loading it from the open provider I still can't get what is different between my 2 projects

My other working application has the following header for each tile:

GENERAL 
  Remote Address:192.163.219.40:80

AngularJS configuration

Cache is disabled.

$httpProvider.defaults.cache = false;

I also tried the following additive as HTTP TILE LOADING are get (not successful)

  //initialize get if not there
    if (!$httpProvider.defaults.headers.get) {
        $httpProvider.defaults.headers.get = {};    
    }    
//disable IE ajax request caching
    $httpProvider.defaults.headers.get['If-Modified-Since'] = 'Mon, 26 Jul 1997 05:00:00 GMT';
    // extra
    $httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
    $httpProvider.defaults.headers.get.Pragma = 'no-cache';

HTML Creation of leaflet directive

  <div data-tap-disabled="true" style="height: 90%; {{iosPlatform ? 'top:10%; position:relative' : ''}}">
    <leaflet id="map" defaults="defaults" center="center"
    bounds="bounds" event-broadcast="events" markers="markers"
    height="100%" width="100%" class="animation" layers="layers"></leaflet>

  </div>

AngularJS Code

angular.extend($scope, {
            center: {
                lat: -2.6273,
                lng: -44.1932,
                zoom: 18
            },
            markers: {},
            defaults: {
                scrollWheelZoom: true
            },
            bounds: {
                southWest: {
                    lat: -2.628074696286876,
                    lng: -44.19960723876953125,
                },
                northEast: {
                    lat: -2.629410211532874,
                    lng: -44.19617401123046874,
                }
            },
            events: {
                map: {
                    enable: ['popupopen'],
                    logic: 'emit'
                }
            },
            tiles: {
                url: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
                options: {
                    attribution: ''
                }
            },
            layers: {
                "baselayers": {
                    "osm": {
                        "name": "Cidade",
                        "url": "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
                        "type": "xyz",
                        "layerParams": {},
                        "layerOptions": {}

                    }


                },
                overlays: {

                }
            },
            controls: {}
        });

When I open my map, I do call the following function :

 $scope.getMyMap = function() {
        var d = $q.defer();
         leafletData.getMap('map').then(function(map) {
            $scope.map = map;
            map.invalidateSize();
            d.resolve(map);
        }, function(err) {

            d.reject(err);
        });
        return d.promise;

    };

After many tests, I finally installed the cordova whitelist plugin and with it, everything is back to normal.

I really don't know yet Why there is this change concerning the whitelist recently. I'll keep you posted if I have other information concerning that change & impacts
