when I run hardhat compile, it return the error:
Couldn't download compiler versions list. Please check your connection.
Caused by: Error: Failed to download https://binaries.soliditylang.org/windows-amd64/list.json

but if open this url on broswer, it will download corretly .
it seems that the CloudFront CDN blocked hardhat download but allow broswer.

npx hardhat compile --show-stack-traces

Download list.json and keep it locally, and download the solidity compiler on the same path.
