We'd like to gather more information about the issue you're running into. A few questions here to better understand what you're experiencing:
1. Does the issue only occur on a specific channel or all channels on your Roku device?
2. What is the exact error message when accessing the channel? Can you provide a screenshot of the issue you are experiencing?
3. What troubleshooting steps have you taken so far to try to resolve the issue? Have you removed the channel, restart the device the add the channel back? Note: Please make sure to restart your Roku device after removing the channel and before adding the channel back to ensure the process is successful.
