Problems with NWA1123-AC PRO/Nebula Blocking Clients at Random

I have scoured the web and the forums and have yet to find a solution.  Our customer is reporting that their devices can see the SSID, try to connect, but are unable to connect to the SSID.  Some devices work for a while, but later get randomly dropped.  The AP is running latest firmware v6.10(ABHD.3), yet problems persist.  Below are the errors we're seeing:

    Hi @KKC ,
    The log 'Hostapd3 +  prev-Auth Failed' means the WPA2 authentication is not successful. It might be caused incorrect password or packet lost during doing the authentication. So, please check the key in authentication password or if there's any retry rate high information at the issue happened time.
    The other log 'WPA authenticator requests disconnect' means there's a problem of connection between the AP and client with unknown reason, so the AP (WPA authenticator) request to disconnect the connection.
    Would you provide more logs for us to check details or check that if there's many wireless health related logs at that time?

    What logs would you like us to provide? 

    Also, I filtered the logs for Wireless Health, and the filter returned no results.

    Hi @KKC ,
    Please provide the log from 2020-09-24 09:30 to 2020-09-24 11:00 to us because we want to check the client connection status at that time. And, would you help to enable the Zyxel support in the HELP> Support request for us to check the configuration settings of the site.
