Remote build failing with network connectivity timeout

I have successfully completed multiple deploys of the project, but builds are now failing with the same error message each time. I have not made changes to fly.toml. This is a REMIX project and builds fine locally on my machine.

flyctl --app my-app-name deploy .

Hi! It looks like a network issue, could be the network connection between the builder host and the npm.
I’d recommend either deleting the builder or installing docker locally and running fly deploy --local-only

Deleting the builder fixed the issue. Thank you!
