Cozi TV is a broadcast network carried by a local TV station. Comcast just passes it on. Maybe they dropped it or something changed. Without knowing your general area and what station was carrying it, it's hard to tell what happened.
For Houston, Cozi should be on KUBE.
According to the Cozi TV web site, that would be Comcast channel 311 or 1178.
