Can you share the time after which connection disconnects? (run
hostapd with -t option for timestamps)
Is the keepalive triggered from hostapd/Apple device/
If you keep some ping running, do you still see the issue?
Can you capture the sniffer trace when the issue occurs?
When "probes" are used for keepalive Some STA/AP's do not consider
then for resetting inactivity timer, and can cause the disconnection.
Instead if we use "qos null data" for keepalive we will see that the connection
