System.Net.Http.HttpRequestException異常將在物理設備上運行xamarin UI測試

我已經創建了一個簡單的Xamarin.Forms（Portable）項目，並在其中包含UI Test項目。但是當我試圖在物理設備上運行測試時，它給了我下面提到的異常。System.Net.Http.HttpRequestException異常將在物理設備上運行xamarin UI測試

Test Name: AppLaunches 
Test Outcome: Failed 
Result Message:

您在使用使用ModernHttpClient？如果你想處理網絡異常，你也可以使用Polly。例如：

conferences = await Policy 
     .Handle<WebException>() 
     .WaitAndRetry 
     (
     retryCount:5, 
     sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)) 
    ) 
     .ExecuteAsync(async() => await getConferencesTask);

而且AsyncErrorHandler是處理異步異常
