Which AP is this (vendor/model)?

Have you tried setting the passphrase here (psk="your secret
passphrase") instead of PSK as hexdump from wpa_passphrase?

Apart from making very sure that the passphrase is correct (and not
getting incorrect value because of SSID, etc., through wpa_passphrase),
there is not really much that can be done from the wpa_supplicant side.
In other words, this may require getting some debug/system log output
from the AP or wireless sniffer trace showing the frames exchanged
between the devices.
