Need help with Nmap scripts

Hey there guys, Today i tried scanning and bruteforcing this server with Nmap scripts. It has FTP and other many ports open. I tried scanning it but it dosent give ANY respond as you can see in the image.
But in the second image, i changed my ip with anonsurf and now when i try scanning and bruteforcing it, it starts scanning but still gives operation not permitted error.
Please help me get to know the reason, that why was it not scanning the server before changing IP.

nmap -Pn -p 21 --script=ftp-brute 192.249.. -d

Thanks, but it didn’t work… I need to get under tor proxy everytime to make it work

is 192.249… an onion site?_
