Xfinity stream not working

I use the Xfinity Stream app almost daily. As of today, it will not let me watch any shows and states that the channel is not included in my subscription. When I look at my channel list on my account the channels are all listed. I have did a system refresh on my online account. I have logged out and logged back into the app. I have also tried to uninstall it but nothing seems to be working. I am also on my home network.
