"https://charts.gitlab.io" is not a valid chart repository or cannot be reached

I'm trying to install gitlab-runner kubernetes via helm as described in docs https://docs.gitlab.com/runner/install/kubernetes.html#installing-gitlab-runner-using-the-helm-chart. When I'm trying to add helm repo helm repo add gitlab https://charts.gitlab.io I get the error: Error: looks like "https://charts.gitlab.io" is not a valid chart repository or cannot be reached: Get "https://charts.gitlab.io/index.yaml": EOF Helm version 3.11.1

Thanks!
