App won't connect to backend

The backend works fine but the app fails to load response data.
Code from ListingScreen.js:

const [ listings, setListings ] = useState([]);
  const [ error, setError ] = useState( false );

  useEffect( () => {
    loadListings();
  }, [] );

  const loadListings = async () => {
    const response = await listingsApi.getListings();
    if ( !response.ok ) return setError( true );

    setError( false );
    setListings( response.data );
  };

Hey.
I just wanted to know if you didn’t not use localhost when setting your assetsBaseUrl

I used my IP like mosh told us to do, followed every step and rechecked everything I think. Even tried both IP4 and IP6.
