Unsupported Media Type when using Web API
<p>I want to use public Web Api from: <a href="https://www.xbtce.cc/tradeapi" rel="nofollow">https://www.xbtce.cc/tradeapi</a>.</p>

<p>So here is a code:</p>

<pre><code>using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    var url = "https://cryptottdemowebapi.xbtce.net:8443/api/v1/public/tick";
    HttpResponseMessage response = await client.GetAsync(url);
    response.EnsureSuccessStatusCode();

    return await response.Content.ReadAsStringAsync();
}
</code></pre>

<p>And result is:</p>

<pre><code>{StatusCode: 415, ReasonPhrase: 'Unsupported Media Type', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
    Server: Microsoft-HTTPAPI/2.0
    Date: Mon, 15 Aug 2016 16:03:45 GMT
    Content-Length: 0
}}
</code></pre>

<p>This error continue even after adding request headers with "application/json". 
Any ideas how to fix this?</p>
