Stucked with reaver

HI!

I’m constantly receiving this message:

[+] Trying pin “12345670”
[+] Sending EAPOL START request
[+] Received identity request

[+] Sending M2 message
[+] Received M1 message
[+] Sending WSC NACK
[+] Sending WSC NACK
[!] WPS transaction failed (code: 0x03), re-trying last pin

with this command: reaver -b bssid -c 8 - i wlan0mon - d 15 -vv

What part of the course is this?

Section 6, Exploiting WPS feature

Try running Reaver with the --no-nacks argument

Now I’m getting this error all the time.
