I get the same error, but from reading in other places, it seems like a 4.3 issue. It also occurs on my old N7 with the 4.3 update, but plays fine on my Galaxy S4.
seems like there's quite a few 4.3 bugs...works fine on my Samsung 3, Nook HD+ & IPAD....just tested the others to make sure I could still login and access tv.
It's an android 4.3 bug I have two devices with 4.2 and twc works. My 1st gen nexus stopped working after the update and I also have the new nexus which also doesn't work. I hope they fix it quick. My kids are complaining.
