Gitlab dependency proxy fails with 500s on v6 Errno::ENETUNREACH
Everyone can contribute. Help move this issue forward while earning points, leveling up and collecting rewards.
Summary
I am trying a pull from dependency proxy container images, on an host with both ipv6 and ipv4 addresses. When the v6 routing happens to be broken then pulls fail with HTTP 500.
Steps to reproduce
Run dependency proxy on an host with both v6 and v4 addresses, and no default v6 route configured.
What is the current bug behavior?
dependency proxy 500s on container pulls
What is the expected correct behavior?
I was expecting v6 network errors to fallback on v4 and retried
