Netflix dose not work. What should i do?

Are you using a VPN? If so, try disabling.

You could also try unplugging the Roku for 30 to 60 seconds or doing a system restart and see if that helps.

Hi, Viktoriia1 

Thanks for posting, and welcome to the Roku Community.

We appreciate you for sharing with us your concern about the Netflix app, and we're here to help. We would recommend performing the troubleshooting step below to resolve the issue.

1. Navigate to the channel tile on the Roku home screen, press the star (*) key on your remote, and choose "Remove channel".
2. Next, restart your device from Settings > System > Power > System Restart (If you do not see a Power submenu, skip to the next step).
3. Once your player/TV starts up again, go to "Streaming Store" on the Home screen, and add the channel back once more.
