I have been flying my Mavic 2 Pro in the KAPA Class D airspace regularly for more than 6 months. Each time I get an authorization using B4UFLY and Kittyhawk. LAANC always works. Now today it doesn't. After I hit Agree & Submit I get the message "Unexpected Error! There was an error processing your LAANC request." I've changed the altitudes, area requested and the times. I checked the information in my Kittyhawk profile. There are no TFRs. I uninstalled and reinstalled B4UFLY. I've rebooted my phone. I've done combinations of all-of-the-above. I keep getting "Unexpected Error! There was an error processing your LAANC request." This is as far as I get no matter what I try. ... no LAANC authorization. I haven't found any internet DJI or FAA chatter about an LAANC problem. Any suggestions?

Ah!  It looks like the system is down nationwide:  "https://www.fox29.com/news/notification-system-for-drone-pilots-down-nationwide-faa-says"  ... but I can't find an official FAA statement.
