Strange HttpClient result

When trying to get data from a Hitbox API I get a strange result. For a one API's command it happens everytime, for the other only sometimes. The result more or less like that (this is the last result I have got):

It's much much longer but it's pointless to copy all of it (about 30000 characters).

My code that I use to get the json result is:

string result;

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri(hitboxApiLink);
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

    HttpResponseMessage response = client.GetAsync(requestString).Result;
    result = response.Content.ReadAsStringAsync().Result;
}

return result;

I used this before:

HttpWebRequest request = (HttpWebRequest) WebRequest.Create(Path.Combine(hitboxApiLink, requestString));
request.KeepAlive = false;
request.ContentType = "application/json; charset=utf-8";
WebResponse response = request.GetResponse();

using(StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
    result = reader.ReadToEnd();
}

And it returns the same. But when I try to get data with Google Chrome or Internet Explorer it returns normal result. The api is: http://developers.hitbox.tv/

The link I try to get data from is: https://api.hitbox.tv/media/live/list

A little off topic, but please don't use .Result and use the await keywoard instead. Using .Result can cause a deadlock if you're not being careful enough with the context and is overall not a good practise when you can use await to unpack the result. Don't Block on Async Code – Kerim Emurla
Path.Combine is for file-system paths. Abusing it for use with URLs will probably lead to trouble. – spender
@KerimEmurla Ok thanks I will change that. – Kuba Wasilczyk
@spender I'm not using this code anymore. It was mostly to eliminate double slash. – Kuba Wasilczyk
Include the response headers in your question – jgauffin

The response is GZIPped (even though this wasn't specified by an Accept-Encoding header in the request, so is technically a fault on the server).

Your second example can be fixed by adding the following line before you fire off the request:

request.AutomaticDecompression = DecompressionMethods.GZip;

This should give you everything you need to figure out how to decompress the response of the HttpClient version.
