Hi, Camilad BCW1!

Welcome to the Roku Community.

Thanks for letting us know about the streaming issues you're currently experiencing on your Roku devices. We'd be happy to suggest some troubleshooting steps to help you get back on streaming.

Before proceeding, may we know if your device recently received any software updates prior to this happening that might have triggered this issue? Also, are you able to navigate to your Home screen?

If so, kindly follow the steps provided below to help you:

Check for software updates on your streaming device

1. Press Home on your Roku remote
2. Scroll and select Settings
3. Select System
4. Select Software update
5. Select Check Now to manually check for updates

• Tip: The System update screen displays the current software and build version, along with the date and time of the latest update.

Reset your network connection

A network reset is helpful if you experience issues with multiple streaming channels or if you are using a Roku voice remote that fails to respond after replacing the batteries. 

1. Press Home on your Roku remote
2. Scroll and select Settings
3. Select Advanced System settings
4. Select Network connection reset
5. Select Reset connection

We also suggest connecting your device to an alternative network connection to see if this will make any difference. Perhaps a mobile hotspot would do.

Please keep us posted on how it goes and we'll go from there.

Best regards,
Carly

Have you tried performing a "System restart" from Settings->System or Settings->System->Power (as appropriate) or just unplugging the power for several seconds.
