could not setup service: could not boot up service using Docker Compose: running Docker Compose up command failed: exit status 18: Get "https://docker.elastic.co/v2/observability/stream/manifests/sha256:cb5affd0ae129264ec0c6b1b8691e1dbd2c6e43961d065d570c2c22b980e3c8e": dial tcp 34.56.16.77:443: i/o timeout

First build failed: https://buildkite.com/elastic/integrations/builds/49175

Start with the vectra_detect system test: udp and the first Buildkite failure linked in the issue. Inspect the Docker Compose service setup and the image-manifest request that timed out, then rerun the failing test to determine whether the failure is reproducible. Done means the test completes successfully without the Docker Compose startup timeout.
