Hey @terrap
Thanks for the post.
To clarify, are you getting the error message 'Network Connection Problem' when you launch any channels installed on your Roku even if the device is connected to your Wi-Fi? Please check your player's network connection by navigating to Settings > Network > About.
We'll be able to assist you once we have further details of your concern.
All the best,
Kariza
