X1 Box Help

Yesterday, I lost internet for a while. Now that it's back on, the X1 Onscreen Guide Favorites List is incomplete. It shows channel numbers, but no channel names. Also, I can't watch any of my saved programs. I get an error message telling me to try later. Are these issues connected to the internet loss yesterday? I unplugged my X1 box and waited a bit, then plugged in. Problem persists, Anything else I can do? Thanks
