Cyber Mentors' Course problem| nmap not working for some reason?

So I've been following The Cyber Mentor's course on Practicle Ethical Hacking and got to the part where i set up kioptrix on my pc and scan it.but when i use nmap from my linux vm

cmd - nmap -T4 -p- -A <ip>

its gives this

Starting Nmap 7.92 ( https://nmap.org ) at 2022-05-15 18:25 EDT
Nmap scan report for 192.168.57.3 Host is up (0.000245 latency).
All 65535 scanned ports on <ip> are in ignored states.

So I couldn't follow along the course.I tried modifying the cmd to this

nmap -T4 -p 22,80,111,139,443 -A <ip>

and got this

I couldn't find anything on why my results are different than TCM's results and decided use reddit.
so please can anyone point out whats I'm doing wrong?
