Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What error (or condition, e.g. blank screen, white screen, 'snow' on screen) happens when you try to stream a CNN station ?
What is the exact and full text of the error message?
This might be one of several things, and the exact error message will indicate it, I think.
OK. That sounds as if you would be well-advised to check with your Roku service provider.
Perhaps CNN channels aren't in your service plan.
Perhaps service plans have shifted their coverage... a shame if so, but it can happen.
And even more likely: your account needs to be checked on, and verified as to channels it covers and pays for and should have access to.
This adds up to a check on your Roku service provider's status as to your account, and also as to CNN channels... since CNN channels all being one network, it's possible also that the CNN network is simply 'down' at the moment... in which case, reporting that to your Roku service provider may get them onto the problem.
I'm not quite sure what the situation is. But CNN stations may be down. How long has the problem with CNN stations been like this?
