S3 stop uploading files iOS - ios

Question

I have 2 application, one in swift and the other in objective-c, I'm using cognito to authenticate with s3 but the last days this feature stop working I down know why, the console of my application say "request timed out" but I don't change anything. the application start uploading but always stops in 39% or 14% and freeze the upload, this is my code:
App delegate:
let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,
identityPoolId:poolId)
AWSLogger.defaultLogger().logLevel = .Verbose
let configuration = AWSServiceConfiguration(region:.SAEast1, credentialsProvider:credentialsProvider)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration
PhotoViewController
let uploadRequest = AWSS3TransferManagerUploadRequest()
uploadRequest.bucket = "bucket"
uploadRequest.ACL = AWSS3ObjectCannedACL.PublicRead
uploadRequest.key = "\(self.userLogin.customer_subdomain)/photos/\(imageName)"
uploadRequest.contentType = "image/png"
uploadRequest.body = url
uploadRequest.uploadProgress = { (bytesSent:Int64, totalBytesSent:Int64, totalBytesExpectedToSend:Int64) -> Void in
dispatch_sync(dispatch_get_main_queue(), {() -> Void in
self.updateLabel(totalBytesSent,totalBytesExpectedToSend: totalBytesExpectedToSend)
})
}
AWSS3TransferManager.defaultS3TransferManager().upload(uploadRequest).continueWithBlock { (task) -> AnyObject! in
if (task.error != nil) {
//failed
dispatch_async(dispatch_get_main_queue()) {
self.dismissViewControllerAnimated(false, completion: nil)
let refreshAlert = UIAlertController(title: "Error", message: "Error al intentar subir el archivo", preferredStyle: UIAlertControllerStyle.Alert)
refreshAlert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(refreshAlert, animated: true, completion: nil)
}
print(task.error!)
} else {
let dic=["file":"\(self.userLogin.customer_subdomain)/photos/\(imageName)"]
let jsonData = try! NSJSONSerialization.dataWithJSONObject(dic, options: [])
let jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding)! as String
let con:URLConnection
con=URLConnection.init()
con.delegate=self
let headers=["X-Auth-Token":self.userLogin.api_token]
con.connect(self.userLogin.customer_url+"/rest/activities/\(self.activity.id)/photos",method:"POST",json: jsonString, headers: headers)
self.imgName = "\(self.userLogin.customer_subdomain)/photos/\(imageName)"
}
return nil
