Xamarin Android HttpClient.GetAsync only works in Wifi but not mobile data?

I've met a strange problem recently. I have Xamarin Android project, every time I call http request using real device with mobile data, it will throw me HttpRequestException, if I am using WiFi, everything is good.

My code of calling HttpRequest is

var url = "some/parameter"
var client = new HttpClient();
client.BaseAddress = new Uri("http://xxx.xxx.xxx");
await client.GetAsync(url);

Following is the detail of HttpRequestException:

Inner Exception: {System.Net.Sockets.SocketException (0x80004005): No such host is known at System.Net.Http.ConnectHelper.ConnectAsync (System.String host, System.Int32 port, System.Threading.CancellationToken cancellationToken) [0x000c8] in /Users/builder/jenkins/workspace/a…}

Error Code: 11001
Message: No such host is known
SocketErrorCode: HostNotFound

StackTrace as below:

I have included these in my Android.Manifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

My mobile data connection is good as I still can access other app using mobile data, I have no idea why there is difference between using WiFi and mobile data especially HttpRequest? What can I do to fix this problem in my project? Any help?
