Netflix error code 11800 ATV4

The error 11800 is an ATV error, it has been seen in the past with Airplay issues and other failures to connect to servers.

During isolation testing we set up and tested ATV4 on Personal Hotspot and the error does not occur.

This indicated an issue between the ATV > Modem > ISP

I had a feeling the issue is DNS related and I am unsure if a recent change on TVOS or Netflix have triggered this requirement.

Apple usually recommends leaving most settings as default or automatic even for DNS.

This won't be a problem if the Modem or Router are configured with the DNS manually input.

In some situations the Modem/Router are also set to Automatic and I believe this is why people are now seeing this issue.

Solution 1:

Obtain your ISP's DNS either from calling ISP, Via the ISP Website, or Account information supplied with the Internet setup.

Once obtained add these details to the ATV4

- Open the Settings app on your Apple TV

- Click on Network.

- Click on your network to view the network information.

- Click on Configure DNS.

- Change to Manual.

- Enter your DNS.

- Press Done and you are good to go.

Solution 1.5:

In the meantime we should be able to test using Google’s free DNS

If you’d like to use Google’s to resolve streaming issues, you can use either 008.008.008.008 or 008.008.004.004 on the Apple TV.

Solution 2:

Refer to ISP to gain assistance with adding/changing DNS server addresses on the Modem Router which should have the same effect as above.

I had the same problem and tried all the solutions which I found at forums. The curious thing was - Netflix worked fine an all other devices except Apple TV.

I solved the problem by checking the DNS number on my other device connected to the same WiFi and manually copying it to ATV in it's DNS settings (even though at all the forums it is recommended to keep DNS settings automatic). Now it works fine. Hope this helps

As i said, Netflix worked fine on all other devices. Moreover, it worked fine on ATV as well until it just stopped working in the middle of streaming a movie. No changes were done to the router DNS settings neither before the problem with Netflix, nor after.

Not sure of your point, your DNS setting was obviously wrong and may well still be, just because something works or worked doesn't mean it's set up correctly or that it will continue to work. I was only trying to explain why automatic may not have worked for you.

Correct, but if you read that whole post the solution was not to use Google's DNS as a permanent fix. DNS needs to be set to auto, but if there is an issue then you need to contact your ISP to get the proper DNS settings.

I had this issue for weeks, tried the solutions here (didnt work for me...i know they might work for others), and I just solved it.

On my case, my Apple TV 4 was on Ethernet, and my transmitting iPhone was on a Wireless Network. They were both on different networks. So, I switched Apple TV to the same network as the iPhone and voilá, it worked.

Pretty simple but I was on blackout for weeks...

Netflix say there is an technical issue which both Apple and Netflix are working on, so far they have not said when it will be resolved.

I am facing the same issue. I have ATV 2 and ATV 4. Netflix works fine on ATV 2 but with ATV 4 I got this error 11800 to stream.

This is a shame

It would be up to Netflix to fix any issues with the app so best to persist with them

Same issue. My internet provider/Netflix/Apple, do not have a solution. Their trouble shooting procedures are useless in this case.

If you are having issues with the app it is up to Netflix to fix so you will need to persist with them

Using Automatic is only going to work when the DNS settings in your router are correct, it would seem they likely aren't in your case.
