unable to pair to my TV using youtube
I used to pair my iPhone to my smart TV using youtube to be able to type my search youtube using my iPhone virtual keyboard. I used to go to the page youtube.com/pair on my phone safari, and it used to work perfectly.
Recently every time I type that in the address bar it starts loading then it goes to the youtube app for seconds then it goes to web helper.centurylink.com.
My iPhone is 4s. I tried from my wife's iPhone 4 and the same happened. I was able however to pair using my android tablet and my Mac.
What can the problem be? How to be able to pair again.
