xfinity remote app not working

Didn't see a sub-forum for the remote app so I guess I'll post here.

I noticed yesterday that my xfinity remote app (ios 14.0.1) was about two weeks behind with my DVR recordings and the TV listings weren't current.  I couldn't find anywhere in the app to do a refresh so I deleted the app from my phone and reinstalled it.  Now, I cannot log into the app.  It goes out to oauth.xfinity.com and then eventually says "Safari could not open the page because the server stopped responding."

Any ideas how to get this fixed?
