Nmap scan time

Hello, I am new to hackthebox. I was just checking out their beginners guide which you get at your first login. I followed it’s instructions, connect to htb network, ran the nmap port scan as written in the guide ( nmap -sC -sV -p$ports 10.10.10.27 ). But, it’s been almost 5 minutes and it’s just stuck there. No result or output. Can anyone help me?

Did you run ports=$(nmap -p- --min-rate=1000 -T4 10.10.10.27 | grep ^[0-9] | cut -d '/' -f 1 | tr '\n' ',' | sed s/,$//) first?

I am not a huge fan of this approach to using nmap, I get that it feels like it has sped up the process but it generates an awful lot of errors.

You might be better using:

nmap -Pn -sC -sV -p- -vvvvvvv --reason --min-rate=1000 -T4 -oA all_tcp 10.10.10.27

(ymmv)
