Search not working - XFinity

I'm using my computer (Chrome Browser Windows 10) to access Xfinity TV. The search function no longer works. I keep getting the following:
"Your Search Was Interupted. A problem occurred during your search. Apologies for any Inconveniece. (Error searcByTerm500)"

This question, "Search not working," is about XFinity-Comcast TV channels, programming, and sports.
