Unable to run squarespace server locally

Hi all,

I'm new to SquareSpace development and need some guidance to make it work locally.

I tried both methods described on site, and also used a real password and an app password. The Java app fails on me, and the node wrapper also fails, but differently.

Toolbelt

This is what happens when I try to login with the toolbelt



This auth url weirdly gives me a 404.

squarespace-server

The server was giving me what seems to be a success feedback (the logo and the url), but the localhost 9000 is giving me ERR_CONNECTION_REFUSED

My system:
Windows 10
WSL 2 (Ubuntu 20)

My store:
It is in Development Mode, and is not a purchased store, as I said I'm starting with SquareSpace.
