HttpRequestException при вызове Api в xamarin

Question

В xamarin я вызываю api, используя библиотеку refit. Я следовал инструкциям , но при вызове исключения был возвращен API. Я не знаю, повлияет ли моя комбинация призмы? Я назвал ручной API, но он также не работает, я также консультировался по inte rnet, но кажется, что все еще не работает. В расширенном варианте Android я устанавливаю реализацию HttpClient на Android, реализация SSL / TSL - по умолчанию (собственный TLS 1.2+). Могу ли я помочь мне?

public interface IMakeUpApi
{
    [Get("/api/v2/items")]
    Task<string> GetMakeups();
}

В MainPageViewModel

var apiResponse = RestService.For<IMakeUpApi>("https://qiita.com");
var makeups = await apiResponse.GetMakeups();
