Code: RLP-999 is what I’m getting when I try to watch something.

Hi, Winston23

Thanks for posting, and welcome to the Roku Community.

We'll provide troubleshooting steps to resolve the issue. But before anything else, we'd like to gather more information regarding this. May we know when you first encountered this issue? Also, have you tried contacting Spectrum directly and inquiring further about this?

Additionally, we recommend following these troubleshooting steps below:

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. 

You can also follow these steps:

1. Turn off your TV. Then disconnect from both your Roku, TV, internet modem router, and any cable box/device for a couple of minutes. 
2. Then wait a bit and then turn on the TV and check.

After performing this, please let us know if you're still experiencing the issue.

All the best,
Kash
