Docker+WSL2 Can't forward port? - socat, connection refused

Hi! I’m running a wordpress site on Devilbox and things are going great.
Have a plugin that requires port 23517 to send logs to a program listening on port 23517 on the windows host.

On docker-compose.override.yml I have added the port to

When the plugin tries to send a log to the host app, on the docker output I’m getting
2021/01/19 12:09:30 socat[1632] E connect(5, AF=2, 16): Connection refused

Could really use some help! Been scratching my head for days!

Thank you!
