PHP built-in web server not working (php -S)

[jotunel]

When I use sudo proxychains nmap -sT -p443,80 -Pn 192.168.37.238
I get

sudo proxychains nmap -sT -p443,80 -Pn 192.168.37.238

On the other window, I have this:

Can you provide the following information?

1. neoreg version used
2. 192.168.37.238 is the system windows?
3. The content returned by curl http://192.168.37.238:8080/tunnel.php

If you use windows to run php and use it for scanning, you should manually adjust the --php-connect-timeout parameter

1. neoreg version 3.8.0
2. Every machine is a Linux VM machine(attacking is kali, the one i am trying to nmap into is kali, .238 is ubuntu and its hosting the tunnel.php. 192.168.37.238 is the Ubuntu VM that I hosted the tunnel.php into.
3. curl http://192.168.37.238:8080/tunnel.php returns nothing.
4. I am not using Windows at all

Into .238 (root directory), I run:
php -S 192.168.37.238:8080
[Wed Apr 6 14:57:54 2022] PHP 7.4.3 Development Server (http://192.168.37.238:8080) started

and I hosted the tunnel.php I produced with the code pivotpassword in my attacking machine.

I tested php -S and it does not work. The reason is that php's built-in web server is single-threaded blocking.

For PHP built-in web server, neoreg currently does not support :(

[jotunel]

Thanks, so what should I do for it to work?
If I set up a simpleHTTPserver, it still does not work and the same errors pop up (<--socket error or timeout!)

Basically, I can't get it to work via the chain.

run a php web server started by apache.
