Issue adding new deployment cluster using ArgoCD CLI

[helloworld466]

I am trying to add a new deployment cluster to ArgoCD using ArgoCD CLI. I have combined both the kube-config files and set current-context pointing to the deployment cluster name.

Using argocd login <node-ip>:<node-port>, I successfully logged into the server.

When I execute the command argocd cluster add <deployment-cluster-name>, it gives the below error:

INFO[0000] ServiceAccount "argocd-manager" already exists in namespace "kube-system"
INFO[0000] ClusterRole "argocd-manager-role" updated
INFO[0000] ClusterRoleBinding "argocd-manager-role-binding" updated
FATA[0030] rpc error: code = Unknown desc = Get "https://<deployment-cluster-name>:6443/version?timeout=32s": dial tcp: i/o timeout
