Cloudpath authorization errors deal with channels that require authentication to a TV provider account and use the Cloudpath service to manage this authentication. The NBC/Universal family of channels are known to user Cloudpath, I don't know if others do.
As a guess..
Can you access your local CBS channel via your Directv account? If not, your local CBS channel may be in a contract dispute with Directv, which is preventing you from logging into CBS using your Directv "tv provider" credentials until the dispute is resolved.
