Error: Station: [MAC Addr] has blocked by Hostapd3, reason 1

KKC

I have a customer with a single NWA1123-AC PRO installed and connected to the Nebula Control Center.  We are receiving numerous reports of devices that are unable to connect to the SSID.  We're running the latest firmware

v6.10(ABHD.3).  We believe we've found the cause of the problems in the event logs, by have no idea how to fix the problem, as the errors are pretty vague.  Searching Google and the forums has not turned up a solution.

Here are the errors in the logs:
