TV App isn't available right now.

I just spoke with Apple about this. It is NOT a network problem. In my case, the last software update didn’t download and install correctly. I Inadvertently interrupted an automatic download in progress. As a result, neither the tv app or software updates have worked since. Apple updates software in the wee hours, but I’m a night owl, hence the problem.

This solution involves resetting your AppleTV. I did not lose any of my apps or data (see #2). However, proceed are your own risk.

1. Be sure to change the automatic software updates (including beta software) to off. (settings/system/software updates)
2. Set ONE HOME SCREEN to ON. This setting enables apple devices on the network to share the same content within the tv app, provided they are using the same AppleID. (settings/users and accounts/iCloud)
3. Reset your AppleTV (settings/system/reset) The rep tole me to try reset first. If that didn’t work (which it didn’t) to try reset and update.
4. Setup your AppleTV. After you've signed into your user and iCloud accounts, you should start to see your previous apps downloading. (Settings/user accounts)

Good luck!

You would need to troubleshoot the local network as well, and try Ethernet to rule out the wifi. Testing it at another location would also help verify. Make sure everything is up to date (12.4.1)

An issue with a 3rd party app would be unreleased and you would need to consult with the developer for a fix on that.

That in itself does not rule out the network issue. You would need concrete evidence to show that the network is operating within good conditions, have you run diagnostics? What were the results? Again, using ethernet would also help to actually rule out any wifi issues, as would testing in another location. Internet connection is one factor, and while that may be perfectly fine that doesn't give any indication as to how the local network is doing.

I am always doing vigorous testing for the forum and haven't been able to replicate this nor has there been any indication that the majority of users are experiencing this. So further investigation would need to occur to see why it is happening for you.

You didn't mention which version of TVOS you are running, if it's on 12.4.1 then that part is fine. However, If it is running version 13 then that would beta software and that would be a completely different story.

I had that problem after AppleTV auto-installed a beta update. It didn’t resolve until the regular update became available. I have since removed my devices from participating in beta updates. I haven’t had any issues since.

I finally got it to update the firmware & that fixed the error message.

This has found to be an issue associated with TVOS 13, which is beta software. Any number of things can occur when running pre release software and you need to give feedback using the method within the beta program.

Unplug the Apple TV from power and let it sit for a minute, then plug it back in. See if that helps.

Are you having issues with any other content?

Make sure DNS is set to auto (settings - network)

Try ethernet

To see a current status of the network get a report from istumbler, netstumbler or similar. Look for signal strength, noise, nearby networks

Test on another network

My own assessment is that there is something wrong with the TV App.

Up until the last update for the Apple TV device, it was fine.

the error says to check the internet connection. But I have my Apple TV 4K on LAN. Not wireless. When I unplug the connection, a different message appears actually saying there is no internet access. So, it’s confusing that it asks to check.

Access to other apps is same.

Diagnostics on the device are good.

I reset my device twice. And I’ve done everything besides delete apps or change significant settings.

the ONE thing I haven’t tried is seeing if there’s a way to update the app. Because I notice on my iphone that occasionally the apps refuse to properly update. I’m thinking the same is happening here and my app is stuck. I did notice that, compared to my parter’s Apple TV, she has a later gen. The menu is slightly different but the same account...

but if any any of you have more recommendations I’d like to know.

im not on beta I’m on whatever the latest version is.

What version of TVOS are you running?

I’m now able to update to the Non-Beta version of tvOS

I have the same problem. All other apps work fine except the TV App. My apple tv 4k is plugged into Ethernet. I have another Apple tv in another room on wifi and the TV App works perfectly. Not sure what to do.

That is based on your own assessment, and is an assumption. As I said there is no evidence to support that theory. As it stands I am unable to replicate these symptoms and it is not something that appears to be happening to the majority of users.

Diagnostics run on the device is not an accurate assessment and does not account for issues, you need to run a proper diagnostics for the network by running stumbler (mac), netstumbler (PC) or similar. You can also choose to take the unit to a different location, including Apple, for testing.

The app is built in and does not update independently as would be the case with 3rd party apps.

Best to actually verify what version of TVOS you are running as opposed to making a guess.

You will need actual data in order to fully rule out your network, however if you want to stick with the theory that it is the app then that is your choice. However, there would be nothing more that I nor anyone else here could do to assist further so if that's the case I will leave you to it.

TVOS 13 is beta software and has not yet been released to the public. The point of installing beta software is to root out issues, and that feedback needs to be given using the proper method as part of the beta program. Discussions of beta software are not permitted here.

What version of TVOS is it running? Try rebooting.
