The above error prompts when am trying to use different ip on the same network but locally it works

[RickdeJager]

The IP that you're giving as an argument is that IP that targets should connect back to.

You can not start a listener on an IP that's not assigned to you. Likewise, starting a listener on localhost is not going to be of any use, unless of course you are trying to attack your own host.

If you're not sure which IP you need, you can try with something like python -m http.server --bind <IP> and see if the target can reach the python listener.

Unless there's an actual issue with this repo, I'll close the issue soon. This just looks you're giving it the wrong IP address.
