S3 index page is empty
Overview
Looking at https://gitlab-runner-downloads.s3.amazonaws.com/master/index.html we don't see a list of binaries that we can download. The list should be something like https://gitlab-runner-downloads.s3.amazonaws.com/v13.1.0/index.html.
It seems that we can still download the binaries, they are just not listed in the index page https://s3.amazonaws.com/gitlab-runner-downloads/master/deb/gitlab-runner_amd64.deb
