Почему .baseUrl (URL) создает sh мое приложение, когда я создаю объект Retrofit?

Question

У меня есть такой код. Я пытаюсь создать Retrofit Builder, но приложение вылетает в строке .baseUrl(BASE_URL), и я не знаю, почему.

import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
import ru.okcode.news.model.endpoints.TopNewsEndpoints;

public class RestApi {

private static final String BASE_URL = "https://api.nytimes.com/svc/topstories/v2/";
private static final String API_KEY = "lvoWYBxHw7wX3hLFntwUA1XhkuCZoOqE";

private static RestApi instance;

private TopNewsEndpoints topNewsEndpoints;

private RestApi() {
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    topNewsEndpoints = retrofit.create(TopNewsEndpoints.class);
}

public static synchronized RestApi getInstance() {
    if (instance == null) {
        instance = new RestApi();
    }
    return instance;
}

public TopNewsEndpoints news() {
    return topNewsEndpoints;
}
}
