AppleTV error 0033 "Not authorized for content"

Some users may be experiencing this still and I found a solution if a 4th Gen Apple TV gives the error "Unable to Authenticate" or "Unable to Receive Authentication for this Content." This happened with me today on all TV subscription linked services even though I had just used it yesterday. HBO Go, FX, ABC, etc.

TO FIX:

Double tap "TV" on Siri Remote and swipe up any open apps, this will close them

Settings> Accounts>TV Provider

Toggle the Apps from "Always" to "Never"

Relaunch the app where the issue had occurred

Restart the activation process with your TV provider credentials

Voila

There are several other threads in this forum discussing this problem with DirecTV. And this really is a DirecTV/ATT problem, since it seems like they haven't bothered to update streaming access consistent with the new ownership. It's probably not their top priority, after all.

Was there formerly a Directv account that was associated with your modem's IP address? There is speculation that Directv is blocking certain IP addresses, maybe those where the service has been cancelled. Try disconnecting your phone from wifi and verifying via the cell connection to the internet. You will have to sign out of the app and sign back in before doing this. Worked for me after nothing else did.

Finally! Thank you this worked!!
