Academy - Issue with Proxying Tools


I do the “Using Web Proxies” module in HTB Academy.
I am completely stuck with “Proxying Tools”.

What we want to do here is to route all web requests made by specific tool through web proxy tools.
I use Burp on and ZAP on

By exemple, if I try to use nmap, I have the response of nmap, but nothing on Burp.

So what to do ? What I have missed ?

Thank you for your help.
