Posting to a php file working correctly on localhost but not webhost service

I have a php script that is coecting to Apple APNS services to send push notifications to specified users. The script works correctly on localhost when I post to it from swift, but when I move the script over to the free web host service (Byet), I am not receiving the notification on my phone. I am also not receiving any errors which is the weird part, also I will mention that when I pass the data directly into the url, the script works correctly, it only does not work when I pass it in from swift. I will post my swift file and php file below. Any help would be greatly appreciated.

SWIFT FILE

let url = NSURL(string: "http://localhost/push/test.php")!
        let request = NSMutableURLRequest(URL: url)
        request.HTTPMethod = "POST"
        let body = "devicetoken=(token)&message=  (PFUser.currentUser()!.useame!) is coming to your event!"
        request.HTTPBody = body.dataUsingEncoding(NSUTF8StringEncoding)
        NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) in

        if error == nil{
            //success
            //communicate back
            dispatch_async(dispatch_get_main_queue(), {

                do{
                    let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary

                    guard let parseJSON = json else{
                        print("error while parsing")
                        retu
                    }

                    let id = parseJSON["message"]

                    if id != nil{
                        print(parseJSON)
                    }

                }catch{
                    print("caugh an error")
                }

            })
        }

        else{
            print(error?.localizedDescription)
        }
        }.resume()
