Hello,
could you add ipv6 support for the registry at registry.gitlab.steamos.cloud / the GitLab instance.
repo.steampowered.com already has v6 support, but unfortunately registry.gitlab.steamos.cloud not.
I use VMs / Cloud instances to run my CI-Pipelines which only have ipv6 adresses as a public ipv4 adresses or v4 Internet access via NAT costs extra :(
