This error usually points to an issue with Widevine DRM not being properly integrated or supported on certain devices. Since it works for some devs but not others, here are a few things to check:
- Device Compatibility – Not all Roku devices support Widevine. Double-check if the affected devices meet the DRM requirements.
- Firmware & Updates – Ensure that both the Roku OS and your app are fully updated, as outdated versions might cause compatibility issues.
- DRM Configuration – Verify that Widevine is correctly set up in your app’s manifest and that all dependencies are included.
- Network Restrictions – Some networks may block DRM license requests, so testing on a different network could help.
- Debugging & Logs – If possible, enable detailed logging to pinpoint where the failure occurs.
For businesses dealing with digital rights management, ensuring compliance with business license requirements is also essential, especially when distributing protected content across multiple regions.
