We have seen a strong decrease in errors for most users. We are seeing some 401 errors still for users using old versions of flyctl.
Users encountering a 401 error and using a version under v0.3.180, should run `flyctl version update` to update to the latest flyctl version.

This issue primarily impacted users deploying apps via the Fly Dashboard, deploys using flyctl versions lower than v0.3.180, and deploys involving building very large images.
