Xfinity stream can't find device

I've been using Xfinity Stream for several months and really didn't have issues until yesterday. Wanted to watch a show on my Vizio TV and when I went to cast, it said that it could not find any devices to cast to. I checked to make sure that both my phone and TV were on the same network. I've restarted my phone and the TV. I've unplugged the TV for 3 minutes 2x. Uninstalled the Xfinity Stream app and reinstalled it. Unplugged the router to reset it. Nothing worked.  I was able to use cast with YouTube, Disney+, and Peacock. Any other suggestions would be appreciated.
