Salesforce SDK no longer working after May 10 refresh - status 302

Hi: After getting a developer token, we have been connecting to box to download audio files in to Salesforce. The following piece of code stopped working after May 10 upgrade. I was told to look for lower-case headers in the response. But still no luck. Can you help? Here is my sample code.

string endPointUrl ='https://api.box.com/2.0/files/'+fileId+'/content';

Http h1 =newHttp();

Httprequest req1 =newHttpRequest();

req1.setEndpoint(endPointUrl);

req1.setMethod('GET');

req1.setHeader('connection','keep-alive');

req1.setHeader('authorization', 'Bearer '+accessToken);

req1.setHeader('content-Type','audio/mpeg');

try {

String fileLocation, extFileURL;

blob fileBlob;

HttpResponse response =newHttpResponse();

if(!Test.isRunningTest()){

response=h1.send(req1);

fileLocation=response.getHeader('location'); // I donot get the header back, get status 302

System.debug('File Loction '+fileLocation);

}
