I doubt the reboot on the Router will work, but like i said there is no harm trying it whilst waiting for nowtv to sort this out.
Like you my nowtv smart box is working fine and at the mo it seems to be ATV box owners who are having the trouble.
same issue, just got told on live chat the technical team is looking to resolve it so seems its a wider issue. I was told to await an email regarding it so hopefully it will get resolved before too long!
Mine is now back up and running
I have the same problem - only just signed up to Now Tv today, watched one episode of The Tunnel and now "auth error" keeps flashing up - how annoying??? Anyone got an answer please???
My Apple TV is suddenly showing an error message “Auth Error Error authenticating your device!” I’ve noticed this mentioned previously in the forum but there wasn’t a resolution I could see. I’ve tried turning Apple TV on and off. I’ve also restarted it. The Netflix and the Prime Video apps are working as normal. Any ideas how I can solve this?
