 Now, inside the file `webarena/openstreetmap-website/vendor/assets/leaflet/leaflet.osm.js`, change `http://ogma.lti.cs.cmu.edu:8080/tile/{z}/{x}/{y}.png` to `http://<public-url-to-your-tile-server>:8080/tile/{z}/{x}/{y}.png` 
 
 > [!NOTE]
-> By default, the `url` in `TileLayer` and `Mapnik` is set to `"http://ogma.lti.cs.cmu.edu:8080/tile/{z}/{x}/{y}.png"`. The official tile server uses `https://tile.openstreetmap.org/{z}/{x}/{y}.png`. You can use that in the two cases as a way to test in case you run into issues during the setup.
