Menu
I can access a URL manually, but get a timeout when using .Net.
I have created a button to duplicate the scenario more easily. Sometimes I get an exception saying the task was cancelled, else a 504 error which follows this code snippet:
private async void Button_Click_1(object sender, RoutedEventArgs e)
{
var url = "http://api.dailyfive.tv/index.php?task=REQUEST_REGIONS&session=TestWin8&app=4&model=TestWin8&ver=1.0.0.7&os=8®ion=";
var output = await ReadHttpResponse(url);
}
private async Task<string> ReadHttpResponse(string url)
{
try
{
using (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(url);
return await response.Content.ReadAsStringAsync();
}
}
catch (Exception ex)
{
}
return null;
}
Here is the result:
<html>
<head><title>504 Gateway Time-out</title></head>
<body bgcolor="white">
<center><h1>504 Gateway Time-out</h1></center>
<hr><center>nginx/1.2.0</center>
</body>
</html>

It looks like the server is sensitive to the client's user agent. When I added these lines to your sample code, the code sprang into life:
client.DefaultRequestHeaders.UserAgent.Clear();
client.DefaultRequestHeaders.UserAgent.ParseAdd("Chrome/22.0.1229.94");
(There may be a better way of doing it - I haven't used HttpClient before.)
As an aside, I hope you're not really swallowing exceptions like that...
