No cameras after Power Outage

After a power outage (and resumption of power), my cameras do not send video clips, even though the Blink Sync Module successfully connects to my WiFi (per the app), successfully connects to the cloud (solid green bar between the module icon and the cloud on the home screen), WiFi was never changed from 2.4GHz, none of the cameras nor the Sync Module were moved, and everything worked well before the power outage. Any suggestions?
