I use repository: https://gitlab.com/charts/gitlab for deploy Gitlab with Helm on Kubernetes.

POD gitlab-runner can't start:

# kubectl get pods --all-namespaces
default          yellow-squirrel-gitlab-runner-5d9d794df5-zfbp6                   0/1       CrashLoopBackOff   7          11m

# kubectl logs yellow-squirrel-gitlab-runner-5d9d794df5-zfbp6

PANIC: Failed to register this runner. Perhaps you are having network problems

When I call (HTTP): https://gitlab.example.local/ I see: default backend - 404

If I call (HTTPS): http://gitlab.example.local/ I see UI

Where is reason in this problem?
