SEND_ALERT: Send FATAL for AP 3502i

[marcelinndiffo106]

Hello everyone. I am having difficulty registering my 4 3502i access points on my WLC 2500 controller. after console access in an AP, I see the fatal send message. I tried to bring the controller date back to 2018, 2012, 2026 but until the controller rejected the AP. I even downloaded the latest version 8.5.182.0 of IOS but still no success. Thanks for your help

 - Have the controller back to current time, date and use NTP. Then if this persists also check the controller-logs when this happens.
