Helm chart repository URL. Schemes: https://, http://, or oci:// (e.g. https://charts.example/helm, oci://registry.example/charts, https://gitlab.example/api/v4/projects/{id}/packages/helm/stable).

Portainer fetches the chart (HTTP index or OCI). This step does not send registry credentials — configure private OCI access in Portainer (registries / namespace access). The host must be reachable from Portainer, not only from Jenkins.

Do not put credentials in the URL (https://user:token@… / oci://user:token@… is rejected).
