I get the same thing on my Roku TV streamer as well as my iPad. The roku keeps defaulting back to the login then fails and tries again. The iPad just gives me errors. Seems like their streaming service is failing today. All my other channels work on the Roku, just the Spectrum TV streamer fails.
Appears that all online tv is down. Not working here for at least an hour. I had TWC, then Spectrum bought them. New name, same sucky service and customer (no) care.
