Please notice:
If your dump tool failed to retrieve a valid 4way handshake or a PMKID, hashcat will fail to recover the PSK.
If your conversion tool (dump file to hash file accepted by hashcat) failed to detect a valid handshake or a PMKID, hashcat will fail to recover the PSK.
BTW:
Full output of hashcat status would be helpful.
