You will need to contact your ISP or do further troubleshooting, leaving on a public DNS is not the solution and will lead to further issues
Apple Event: May 7th at 7 am PT
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.
A note in support of Vazandrew here, Google DNS is not a solution, it may appear to help but will likely make other things work more slowly too, at best it's a temporary solution.
Thanks, I'll stay tuned for the proper fix, pardon my ignorance but Netflix is working for now so yahoo!
Without reading through the whole thread again, I'm pretty sure someone has already given you a proper fix, get the proper DNS settings from your ISP.
They gave me googles universal DNS 008 008 008 008, this not proper because it is public? Perhaps they will figure out a proper one in future...
Double tap the home button... flick up all the open apps.... restart Netflix...
Worked for me
EDIT (to my last post): Unfortunately, the error persisted. Still, you can try my "fix" and see if you're lucky.
