GTN 650xi not showing ASOS anymore

Hello -- While on a flight yesterday, I noticed that my GTN 650xi was not showing the AWOS weather station at my destination airport.  I would lcikc "Waypoint info > Weather" and it said something like "Weather Not Available".  It remained this way for the next hour and until I landed.  On the FIS-B status page, several other weather products were showing up (green), while METARS are white (awaiting data).

How could I be receiving several weather sources, but not AWOS at my destination?

Thanks
