Ok, emergency over. I finally got it connected with the hub, and that’s good enough. Just iOS not working then.

I’m having the same problem. I had it connected but changed my router and the flic-IKEA connection stopped working. Thought I’d just remove and reconnect; that was a big mistake. Security code hasn’t been accepted for three days now and I rely on this for all my lighting, so you can imagine the inconvenience...
