Spectrum not working on Roku - TWC TV and Apps

A few weeks ago the Spectrum app suddenly stopped working on my Roku 2. Whenever i open it i am taken to a screen where i choose to either watch tv, subscribe, or view tour. when i hit watch tv it says "We apologize, but we are unable to fulfill your request at htis time. Please try again later." it works fine on my computer. Whats up??

This question is about "Spectrum not working on Roku", with Time Warner Cable TV and apps.
