To use Zattoo reliably on your LG Smart TV, make sure both the Zattoo app and your TV software are up to date.
Follow the steps below in the given order and only move on to the next one if the issue persists.
Note: Menu names may vary slightly depending on your model and webOS version.

1. Important note on device support
Zattoo availability on LG Smart TVs depends on the model year, webOS version and country of use:
Germany & Switzerland: LG models from 2016 onwards (webOS 3.x and newer)
Austria: LG models running webOS 4.x and newer
If your LG TV is older or uses an earlier webOS version, the Zattoo app may not be available in the LG Content Store. Issues on unsupported devices cannot be resolved.
2. Fully close the Zattoo app
On LG Smart TVs, it can help to completely close the app:
Open another app (for example Settings or LG Content Store).
Then reopen Zattoo.
If available, also close Zattoo via the app switcher (Home menu).
3. Restart the TV (soft reset)
Restarting often resolves temporary issues.
Unplug the TV from power for at least 60 seconds.
Plug it back in and turn it on again.
4. Update the Zattoo app
Open the LG Content Store.
Search for Zattoo.
Install an update if available.
5. Delete and reinstall the Zattoo app
Press Home on your remote.
Go to Apps.
Select the Zattoo app.
Choose Delete or Uninstall.
Restart the TV.
Reinstall the app from the LG Content Store.
6. Update the TV software
Go to Settings → All Settings.
Select Support → Software Update.
Install an update if available.
Restart the TV afterwards.
7. Optimise your network connection (LAN recommended)
For stable streaming, we recommend using a wired LAN connection (Ethernet) if possible. A wired connection is generally more stable than Wi-Fi.
If you are using Wi-Fi:
Use the 5 GHz band if available.
Place the router as close as possible to the TV.
Restart your router.
Test another network (for example a mobile hotspot).
Please note:
Public or hotel Wi-Fi networks may block or restrict streaming.
Mesh systems may cause connection switches depending on configuration.
Further tips can be found in our Improve streaming quality article.
8. Disable VPN, proxy or DNS filters
Zattoo may be blocked if your connection is routed through services that mask or redirect your IP address.
Disable any active VPN or proxy (including router-level VPN).
Check whether DNS filters (e.g. Pi-hole or ad blockers) are active and disable them for testing.
Restart both your router and TV.
9. Change DNS settings
If connection issues continue, you can test a different DNS server.
Go to Settings → Network.
Select your connection (Wi-Fi or Ethernet).
Open Advanced Settings.
Set DNS to Manual and enter 8.8.8.8.
Restart the TV and test Zattoo again.
10. Reset the LG Smart TV to factory settings
If none of the previous steps resolve the issue, you can reset the TV completely.
Go to Settings → All Settings.
Select General → Reset to Initial Settings.
Confirm the reset.
Note: All installed apps and saved settings will be removed.
