Pull bug

[IonBoleac]

What happened: When I try to register in pull mode a cluster situated in a VM ubuntu server VirtualBox with the IP address 192.168.56.104 the output is:
kubectl karmada register 192.168.56.103:32443 --token **** --discovery-token-ca-ce
rt-hash sha256:****
[preflight] Running pre-flight checks
[preflight] All pre-flight checks were passed

W1002 23:43:19.955485 6699 register.go:349] Failed to remove bootstrapKubeConfigFile: remove /etc/karmada/bootstrap-karmada-agent.conf: no such file or directory
error: couldn't validate the identity of the API Server: Get "https://192.168.56.103:32443/api/v1/namespaces/kube-public/configmaps/cluster-info?timeout=10s": tls: failed to verify certificate: x509: certificate is valid for 127.0.0.1, 10.0.2.15, 79.18.53.33, not 192.168.56.103

The first line of init command are:
sudo kubectl karmada init --kubeconfig config
I1002 23:20:51.327231 96917 deploy.go:255] kubeconfig file: config, kubernetes: https://192.168.56.103:16443
W1002 23:20:51.368141 96917 node.go:52] The kubernetes cluster does not have a Master role.

I1002 23:20:51.376886 96917 deploy.go:275] karmada apiserver ip: [10.0.2.15]

How can I resolve this problem?

Environment:

• Karmada version: latest
• kubectl-karmada or karmadactl version (the result of kubectl-karmada version or karmadactl version): latest
• Others: I use a VM with ubuntu server and the cluster is created with microk8s. To run VM I use Virtual Box.
