我在下面复制了异常。我已经通过VPN连接了Android设备，如果VPN连接失败，则FlurlHttp调用给出了未处理的异常。我正在Xamarin.Android上开发应用程序。如果设备通过VPN连接，则可以正常工作。请有人提供一些解决方案，如何处理。
如何使用Flurl Http调用获取响应StatusCode（200）？

最佳答案
请求未完成。 TaskCanceledException表示它已被明确取消（通过CancelationToken），或者更有可能发生了超时。它会在抛出异常之前旋转一段时间吗？更有可能是超时。 Flurl的默认超时为100秒，但是您可以将其configure设置为其他超时。
另外，如果可能的话，我强烈建议您upgrade Flurl.Http。您正在使用非常旧的版本。
