ganache local corresponds to a ganache UI instance, doesn't it?
So As I've commented on the other thread, please go to your ganache setting and change the server to WSL

remember when you change the ser rpc server to wsl, the http address is going to be different, so please add the network again with the new http address.

O it's true, I'm not comfortable yet ...
So i remake the network :

SUCCESS: A new network 'ganache-local' has been added
  └─ganache-local
    ├─id: ganache-local
    ├─cmd: ganache
    ├─cmd_settings: {}
    └─host: http://172.24.192.1

But when i launch the script and i get always the same problem.

preferably you should close the ganache cli before opening the ui one, they uses the same ports and could get on conflict

I opened Ganache UI before Visual Studio Code.
And i did not get the WSL server in the hostname section.

After i opened Visual Studio Code with the project on WSL, and after that i can get the vEthernet(WSL) host name on the UI.
So i select it, and i get always the same problem when l aunch the command

You should have running the WSL server before opening ganache...
Still this error si really strange, have you any thoughts on this @PatrickAlphaC ?

Juste before i had to delete the folder ganache present on %APPDATA.
Now i closed VSC and i opened Ganache UI and i can acces to WSL hostname.
After i opened VSC to launch brownie run scripts/deploy.py --network ganache-local Brownie v1.18.1 - Python development framework for Ethereum but i have always the error

Could you make this a stack exchange ETH question? It might be something odd going on.
