DelegatingHandler переопределить SendAsyn c возврат 404 при вызове URI субдомена

У меня настроен прокси-шлюз для вызова API-сервера со следующим классом DelegatingHandler SendAsyn c, который работает путем вызова с именем сервера HTTP или по IP-адресу HTTP, но возвращает ошибку 404, вызывая субдомен 

public class ProxyHandler : DelegatingHandler
{ 
    protected override System.Threading.Tasks.Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
    {
        var pathandquery = request.RequestUri.PathAndQuery;

        // APPserver webapi URL
        var uri = "http:localhost/api/";

        request.RequestUri = uri;

        if (request.Method == HttpMethod.Get)
        {
            request.Content = null;
            return base.SendAsync(request, cancellationToken)
                   .ContinueWith<HttpResponseMessage>(t =>
                   {
                       var response = t.Result;
                       response.Headers.Add("Access-Control-Allow-Origin", "*");

                       return response;
                   });
        }
        else
        {

            if (request.Method == HttpMethod.Post)
            {

                return base.SendAsync(request, cancellationToken)
                  .ContinueWith<HttpResponseMessage>(t =>
                  {
                      var response = t.Result;
                      response.Headers.Add("Access-Control-Allow-Origin", "*");
                      response.Headers.Add("Access-Control-Allow-Credentials", "true");
                      response.Headers.Add("Access-Control-Allow-Methods", "POST");
                      return response;
                  });
            }

            if (request.Method == HttpMethod.Put)
            {

                return base.SendAsync(request, cancellationToken)
                  .ContinueWith<HttpResponseMessage>(t =>
                  {
                      var response = t.Result;
                      response.Headers.Add("Access-Control-Allow-Origin", "*");
                      response.Headers.Add("Access-Control-Allow-Credentials", "true");
                      response.Headers.Add("Access-Control-Allow-Methods", "PUT");
                      return response;
                  });
            }
        }
        return base.SendAsync(request, cancellationToken);
    }
}

API работает через браузер с https и поддоменом, но возвращает обработчик ошибки 404 через обработчик делегата sendasyn c. запрос выглядит следующим образом:

запрос с именем сервера или I адресом - работает

Ответ

Но ответ 404 ошибка через поддомен (который работает через браузер или почтальон) Запрос
