Hi,

This error generally pops up when there is a TCP Connection problem meaning that your CLI cannot connect. What you should try to do is this :

1. Close the actual Terminal you're using ( Bash, Zsh, WSL ) and make another one
2. in the temrinal type : foundryup
3. Before trying on Gananche try to use the --rpc-url with anvil first by opening a second terminal and typing anvil use the rpc url of it generally it's : http://127.0.0.1:8545
4. Restart VsCode
5. Be sure to verify you have a solid connection and that you're not far away from a wireless device for example
6. Restart the Computer

Try this

To solve this issue u have to open a new terminal with same directory to initialize Anvil so to show it is running already

And your code line is not complete due to using interactive is to the fact there should be a private key that you should either use .env or using the latest keystore method

Or if you don't want to do that u can just compile it by using forge create SimpleStorage it will automatically create using anvil default way but when u need to specify with private key follow the steps I gave you

if u use the wsl in vs code, you have to make sure ganache also in wsl, so you need to create a new wroking space in ganache und change it to wsl

Thanks for the tip!
