1. Why does this message appear?

Some broadcasters (e.g. channels of the RTL Group) use enhanced DRM and HDCP protection requirements.

These are technical copy protection measures. Zattoo has no influence over these broadcaster security requirements.

If your device or device setup does not meet these requirements:

• the stream may be blocked

• the video quality may be reduced

2. Check external monitors or HDMI connections

DRM/HDCP issues are often caused by:

• external monitors

• HDMI adapters

• USB-C hubs

• docking stations

• certain HDMI cables

Please test the following:

• disconnect external monitors (if applicable)

• remove adapters or hubs

• try a different HDMI cable

• try a different HDMI port

3. Windows (Web or Windows App)

Recommended setup:

• Windows 10 or higher

• Latest version of Microsoft Edge

Please check:

• Install Windows updates

• Disable browser extensions

• Disable ad blockers

• Close screen sharing or recording tools

• Disconnect external monitors (if applicable).

Chrome, Firefox or other browsers may cause issues with certain channels.

4. macOS (Web)

Recommended setup:

• macOS 10.14 or higher

• Latest version of Safari

Please check:

• Update macOS

• Disable browser extensions

• Close screen sharing or recording tools

• Disconnect external monitors (if applicable).

Other browsers may have limitations with DRM-protected content.

5. Android and iOS (App)

Please check:

• Use the official Zattoo app from Google Play or the Apple App Store

• Do not use Zattoo in a mobile browser

• Device must not be rooted

• Do not use external displays via HDMI or USB

• Disable VPN, proxy or Private Relay

• Disable ad blockers

Uncertified or uncommon Android devices may not be compatible.

6. Linux and Kodi

Linux is not officially supported. Error-free playback cannot be guaranteed.

Using Zattoo via Kodi or similar software is also not supported and may result in DRM/HDCP error messages.

7. Important note

If your device does not meet the DRM/HDCP technical requirements, Zattoo cannot provide an alternative solution.

In this case, you will need to use an officially supported device.
