Hi Guys,
I am working on sync file from box to another source. Almost 3 weeks ago, we found there are lots of download file API timeout issue was occured in our production. I am try to print the error log.

this is our code to use the Box sdk

~~~ C#
private Stream BoxExecuteBasicRequest(string fileId, long startByte, long endByte)
{
Stopwatch stopWatch = Stopwatch.StartNew();
var url = string.Format("https://api.box.com/2.0/files/{0}/content?Range=bytes={1}-{2}", fileId, startByte, endByte);
IRequestHandler handler = new HttpRequestHandler();
var service = new BoxService(new HttpRequestHandler());
try
{
BoxRequest boxrequest = new BoxRequest(new Uri(url));
boxrequest.Timeout = TimeSpan.FromSeconds(1200);
var responseResult = service.ToResponseAsync<Stream>(boxrequest).GetAwaiter().GetResult();
if (responseResult.Status == ResponseStatus.Success)
{
return responseResult.ResponseObject;
}
else
{
return this.ResponseErrorHandler<string>(boxrequest, responseResult);
}
}
catch (Exception ex)
{
stopWatch.Stop();
LogFactory.GetLogger(LogType.ExternalContent).Error(
"ExternalContentSync BoxApiWrapper ExecuteBasicRequest exception {@Detail}, Request duration {requestDuration} ms", new
{
url,
ex.Message,
ex.StackTrace
}, stopWatch.ElapsedMilliseconds.ToString());
throw;
}
}
~~~

We were change the timeout to 1200 seconds in BoxRequest object, but we still occured the timeout issue, and request was pended 1200 seconds.
