Yes, it looks like the station is able to receive the
EAP-Request/Identity from the AP and at least wpa_supplicant is trying
to send out the response. Since hostapd logs did not show that response
arrive, it is being dropped somewhere in the path from wpa_supplicant to
host.

A wireless sniffer could be used to confirm whether the frame was really
sent by the driver.

Which WLAN driver are you using on the AP and how is the network
configured as far as bridging is used (i.e., is the WLAN netdev in a
bridge)?
