Starting point "Redeemer": Host seems down

Here’s what I’m getting trying to nmap that one:

:~# nmap -p-
Starting Nmap 7.80 ( ) at 2022-12-08 00:10 UTC
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 3.16 seconds

Am I doing something wrong or is that an error on the HTB side?

Try this sudo nmap -p0- -v -A -T4 address
