GitLab Runner on kubernetes missing repo

I am trying to install a gitlab-runner on kubernetes. I am trying to follow the gitlab documentation. I am trying to install the helm chart. when I copy paste the command on your site, I get the following.
"
helm repo add gitlab https://charts.gitlab.io
Error: looks like “https://charts.gitlab.io” is not a valid chart repository or cannot be reached: Get “https://charts.gitlab.io/index.yaml”: unexpected EOF
"

Is there an updated helm chart?

thanks,

The error reads like an intermittent network problem where the chart repository fetch was interrupted.

For testing, can you run curl https://charts.gitlab.io/index.yaml and see whether you can download the file content? If not, suggest checking the network path/route/firewall.
