It looks like hostapd is sending out EAP-Request/Identity to the
station, but does not receive any response to that. That message made it
to the station based on this:

But it is not clear what the station did here, i.e. whether it tried to
reply or not.. This would require either getting more detailed debug
information from the station (e.g., enable wpa_supplicant debugging and
check logcat if this is on Android) or a wireless sniffer capture of the
frames exchanged between the device (to check whether the station
replied with EAP-Response/Identity).
