This usually means something is wrong with your netflix account. I had that happen after I changed my password and reset devices. It took a few days for the reset to take (a serious security flaw on their end if you ask me) and then that popped up. I had to go back to Netflix, reset devices again, delete the channel, then re-add it. Note that I had to reset devices AGAIN (another flaw on their end.)
Nun sacciu, nun vidi, nun ceru e si ceru durmiv.
I know nothing, I see nothing, I wasn't there,
and if I was there, I was asleep.
