Unable to connect with samsung ue55ks9000
Hi, I can reach connection with TV :( 

Here is a debug log: https://pastebin.com/x9cvfDw2

Strange is that when Homebridge return message: "Pair failed. Make sure you click Allow on the TV!" I can turn tv off and on from home app. But it works occasionally.
