WeatherFlow: Device offline

My 2 week old weather station reported "device offline last night. I checked the hub and it was connected. The app reported connection but there were no readings overnight. I performed ALL app, router, wifi reboots etc all without success. Finally I had to reset the weather station, delete from the app the station and add it back to reconnect. The settings are all within printed range. What happened and how do I correct for it. The hub is less than 30-40 feet from the station.
