Hi @AlanMi As the error message states, Bazel could not connect (Connection timed out to download the [https://raw.githubusercontent.com/commercialhaskell/all-cabal-hashes/6638293ee2c7346e93b00c3922c401e0e41c508b/Glob/0.10.1/Glob.cabal](https://raw.githubusercontent.com/commercialhaskell/all-cabal-hashes/6638293ee2c7346e93b00c3922c401e0e41c508b/Glob/0.10.1/Glob.cabal) file it needs to build the dependency. This issue may be intermittent and then you should succeed on a retry, otherwise you need to ensure that your machine is not blocked from accessing the file. ---

Perhaps also worth pointing out that you only need this if you want to hack on the Daml source code. If you just want to use the Daml SDK, you can use the Windows installer from [Release 1.17.1 · digital-asset/daml · GitHub](https://github.com/digital-asset/daml/releases/latest/) ---

But still get the same error message when you try to build? ---
