CFNetwork SSLHandshake failed (-9807) - firebase

Question

I keep receiving this error, CFNetwork SSLHandshake failed (-9807), in the debug window and have no data displayed when trying to populate a UITableViewController with Firebase data. I have tried this potential solution iOS 9 ATS and Firebase REST but still have the issue.
The code I am using is (Credit to #DavidEast)
class TableViewController1: UITableViewController {
// your firebase reference as a property
var ref: Firebase!
// your data source, you can replace this with your own model if you wish
var items = [FDataSnapshot]()
override func viewDidLoad() {
super.viewDidLoad()
// initialize the ref in viewDidLoad
ref = Firebase(url:"https://the-lighthouse-app.firebase.io/states")
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
// listen for update with the .Value event
ref.observeEventType(.Value) { (snapshot: FDataSnapshot!) in
var newItems = [FDataSnapshot]()
// loop through the children and append them to the new array
for item in snapshot.children {
newItems.append(item as! FDataSnapshot)
}
// replace the old array
self.items = newItems
// reload the UITableView
self.tableView.reloadData()
}
}
}
