Error HH502: Couldn't download compiler version list. Please check your internet connection and try again

I am following the process from https://hardhat.org/tutorial/creating-a-new-hardhat-project to create a new hardhat project. However, it is throwing an error in the contract compiling step; i.e. when I run yarn hardhat compile

Downloading compiler 0.8.9

I'm running the code on windows with WSL using

node v16.13.2
yarn v1.22.15
hardhat v2.11.2

Here are my WSL configs

BUILD:    19042
BRANCH:   vb_release
RELEASE:  Ubuntu 20.04.3 LTS
KERNEL:   Linux 4.4.0-19041-Microsoft
UPTIME:   0d 3h 18m

Here's my hardhat.config.js

require("@nomicfoundation/hardhat-toolbox");

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.9",
};

Here's my repo link: https://github.com/J0SAL/hardhat-simple-storage

Solution

  • The code and everything are correct.

    I found the issue in my WSL setup.

    Right now I'm using Windows PowerShell and it's working fine.
