Gitlab runner won't start?

Hello,

I’m using the gitlab.com, not the self-hosted one, and I had for a long time my K8s cluster added to my project and all was working nicely.
Recently I’ve setup a new cluster and I tried to essentially do the same thing and add the new cluster to gitlab but it simply doesn’t work… like nothing happens when I add it…
I followed the documentation here: Add an existing Kubernetes cluster | GitLab
created the tokens, checked the CA certs all that, on the gitlab page I see no errors at all it’s like it was working, but runners don’t appear and I checked my k8s and I have no new namespaces nor resources, it’s like gitlab added the cluster but didn’t trigger the setup or something…

I also tried to add the gitlab to my old cluster, where it was working before and again, not working… same behaviour.

I also tried to “Enable Prometheus integration” to see if it would do any change on the k8s and same thing… nothing happened…

Since I have no error logs no nothing I have no clue what to look for…

Any ideas?

Thanks.
