Unable to authenticate every morning (spesific time)

[andi_achridhan_]

Hi Experts..
I have 86 Access Point that have same problem every morning, most client cant login authentication and connect until 10am while some other (only 1 per 8 client) can login before that time

Im using 3 Active Directory for AAA Servers

I had try to ping each Access Point ip's reply
ping AAA server ip from Network Connectivity reply
try Test Authentication/Accounting Servers login for each AD and success

this is weird because this issue only before 10am everyday and solve itself without changing any configuration

how to check and solve this issue..

here events what I got

Any firewall rules with scheduling policies?
