scanning 10.20.7.2 with nmap: no result

[listhai]

Hello everyone, I hope someone can help me.

nmap is ok [root@test9 module]# nmap 10.20.7.2 Starting Nmap 6.40 ( http://nmap.org ) at 2023-12-09 16:56 CST Nmap scan report for 10.20.7.2 Host is up (0.00062s latency). Not shown: 996 closed ports PORT STATE SERVICE 22/tcp open ssh 3300/tcp open unknown 6789/tcp open ibm-db2-admin 6839/tcp open unknown Nmap done: 1 IP address (1 host up) scanned in 8.17 seconds

But when executing the NetDiscovery task, nmap: no result appears. Why? Somebody can help me ? Thanks in advance.
