docked flask / waitress.serve not visible in local network

I have my server running under docker and start it with the command serve(app, listen='*:5000').

I can:

• access it in container under both 127.0.0.1:5000 amd localhost:5000
• access it from outside the container under localhost:5000

I cannot:

• access it from outside container under '127.0.0.1:5000'
• access it from local network using local ip (and this is what matters the most to me)

I was trying to pass the local address into the serve command but it throws error saying that the address cannot be accessed. Also tried the host='0.0.0.0'. Did not help.

Would anyone know how to make it visible outside of my machine?

ok so i found a solutions that seems to do the trick. the problem was wsl. at github wsl repo there is a script that sets a bridge. below i post the code so it does not perish. credit to edwindijas

$found = $remoteport -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';

if( $found ){
  $remoteport = $matches[0];
} else{
  echo "The Script Exited, the ip address of WSL 2 cannot be found";
  exit;
}

#All the ports you want to forward separated by coma
$ports=@(80,443,10000,3000,5000);


#[Static ip]
#You can change the addr to your ip config to listen to a specific address
$addr='0.0.0.0';
$ports_a = $ports -join ",";
