Error msg="error syncing 'rancher-charts': handler helm-clusterrepo-ensure

Hi Everyone.

I have a strange issue after upgrading to Kubernetes v1.28.9 and rancher 2.8.4 from Rancher 2.7.6 and Kubernetes v1.23.16, we have one cluster attached and it reports the following.

"level=error msg=“error syncing 'rancher-charts”
error: exit status 128, detail: fatal: unable to access ‘https://git.rancher.io/partner-charts/’: Failed to connect to git.rancher.io port 443 after 2058 ms: Couldn’t connect to server\n,

The rancher-charts works as expected on the local cluster. It seems Cluster agents is not connecting correctly to the local cluster.

RHEL: 8.9
Docker: v24.0.6
K8: v1.28.9
Rancher: 2.8.4
