How to collect debug level logs from gitlab-runner-helper?

This is the error I’m getting intermittently. About 70% of the time. Retry the job (maybe a few times) and it works.

The runner is in our Kube/openshift cluster. It is accessing the https://gitlab.com server. There is no proxy server involved. I do not believe there is a cert issue with https://gitlab.com

What other connections may this be released to?

Sometimes this error comes when

  • Preparing environment
  • Getting source from Git repository
  • Uploading artifacts for failed job
  • Uploading artifacts for successful job

The Self-signed certificates or custom Certification Authorities | GitLab doesn’t help because there are no self-signed certs in, and it is intermittent.

I have the runner in log_level=debug, but that is not is not giving me debug logging for the gitlab-runner-helper which I think is where the issue is coming from.
