File uploading not working on Win phone 8 3G connection


I have a app in which user can record video and an api to upload recorded video to azure. I am using below code

HttpClientHandler handler = new HttpClientHandler(); handler.MaxRequestContentBufferSize = int.MaxValue; using (HttpClient httpClient = new HttpClient(handler) { MaxResponseContentBufferSize = int.MaxValue }) { MultipartFormDataContent content = new MultipartFormDataContent(); content.Add(new ByteArrayContent(chunks), "file", fileName); HttpResponseMessage response = null; response = await httpClient.PostAsync(new Uri(url), content); return await response.Content.ReadAsStringAsync(); }

This is working only when either connection is wifi or on 3G video is less than of 10 sec. When I tried to upload video of size around 20-30 MB than it fails. In response I got status code 404 Not Found.

I also tried another way to upload but caught same error.


At last, I have changed my api code and send request with 1 mb chunks.
