We reviewed some APs and all of them show the same reason for problem, CAPWAP was lost form Aps, this is reason for AP disjoin, this confirms the problem is WLC did not received control packets and keepalive packets from APs, this is reason for issue.

- Checkout the overall health of the APs using commands from https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/217738-monitor-catalyst-9800-kpis-key-performa.html#anc4

Also have a checkup of the controller's configuration using the CLI command show tech wireless and feed the output from that into : Wireless Config Analyzer
