This only happens when using Ethernet, Wi-Fi is fine.

I have read quite few suggestions and solutions but non have worked.

This is what I have tried:

1. Turn off both Apple TV and the TV.
2. Then unplug both Apple TV and the TV for two to three minutes.
3. Plug both devices back in.
4. Turn on both devices.
5. Try Netflix again.

Approach #2 (unsuccessful)

1. Manually set and try Google public DNS which is 008.008.008.008

Approach #3 (unsuccessful)

1. Uninstall and reinstall Netflix.

Approach #4 (unsuccessful)

Approach #5 (unsuccessful)

I'm still getting the 11800, has anyone found a solution for this?
