Hi there! I see you’re getting an Error code -3 when streaming the WAND NOW app on your Roku stick connected to your LG TV. Let’s get to the bottom of this together.

To start, could you tell me if this error happens immediately when you launch the app, or does it occur after some time into streaming? Also, have you tried any fixes already like restarting the Roku or your LG TV?

In the meantime, here's a step-by-step plan we can try:

1. Restart your Roku and LG TV: Unplug both devices from power for about 30 seconds, then plug them back in. This can clear temporary glitches.

2. Check your internet connection: Make sure your Roku has a stable internet connection. On Roku, go to Settings > Network > Check connection.

3. Update the WAND NOW app: Sometimes app errors happen due to outdated versions. On Roku, highlight the WAND NOW app, press star () on the remote, and select “Check for updates”.

4. Reinstall the app: If updating doesn’t help, remove the WAND NOW app from your Roku and reinstall it. Go to Roku’s Home screen, highlight the app, press () then choose Remove, then re-add it from Roku Channel Store.

5. Check for Roku system updates: It’s helpful to keep your Roku system updated. Go to Settings > System > System update > Check now.

If these steps don’t clear the error code -3, it could point to a more specific issue with the app’s streaming permissions or server-side problem.

Would you be comfortable trying these steps now? Let me know if you need help with any specific one!
