Learning ethical hacking from scratch, wps transaction failed (code: 0x03) and (code: 0x02) and WARNING: Receive timeout occurred error

I recently started this course and I am in Hacking the WPA/WPA2 without a wordlist, lecture, and when I run reaver with aireplay-ng I get these messages(reaver): WPS transaction failed (code: 0x03) and (code: 0x02), and WARNING: Receive timeout occurred error. I am not sure what to do, I’ve been trying to figure it out by myself all day, but have had no luck. It just keeps retrying the pin without moving on to the next one. So I was wondering can someone hear help me out.

Usually, the WPS thing fails when you are too far from the router. The other reason would be your router preventing from sending WPS codes so quickly
