Git-LFS and custom Certificates Authority - x509: certificate signed by unknown authority

We're trying to use a minio instance as a backend for git-lfs. Our minio instance is served over https with a certificate signed by our internal CA. We have instructed our gitlab deployment to use our CA using documentation https://docs.gitlab.com/omnibus/settings/ssl.html#install-custom-certificate-authorities. Our CA is well listed in the /opt/gitlab/embedded/ssl/certs/ folder. We have successfully triggered some webhooks to some other services using the same CA - with SSL verification enabled.

However, when gitlab-workhorse execute the handleStoreLFSObject it fails with "x509: certificate signed by unknown authority".

How can we we instruct gitlab-workhorse to trust the same CA bundle as the rest of GitLab parts?

Sample logs:
