Hi @CoachK1102,
Welcome to the Roku Community.
Have you tried to remove the channel and see if it helps? If you haven't tried it yet, you can remove the affected channel and re-install it. To ensure the process is successful, restart your device before adding the channel back in. We would recommend doing this from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
You may also refer to this Support link: How do I resolve channel playback issues?
If you need additional support, for more information about that specific error code, visit Spectrum's support page here.
Regards,
Nimfa
