This looks like hostapd is trying to send out the first message of the
WPA 4-Way Handshake, but does not receive any reply to this. Have you
tested this AP with any other client? It would be useful to know whether
the 1/4 msg is received by the client at all and if yes, whether the
client actually replies to it. Just based on the hostapd log alone, I
cannot tell what exactly is causing the problem since either of the
messages could be lost at many different location in the path.
