### Cluster information:

Kubernetes version: 1.30

**bare-metal**  
Installation method: **standard**  
Host OS: ubuntu 22.04  
CNI and version: **I used calico**  
CRI and version: **containerd://1.7.12**

Hi, I have just setup local cluster master and 1 node (2 ubuntu 22.04 VMs), everything went fine and was able to see the 2 nodes when I run “kubectl get nodes” both on ready state from master and node1. However, after rebooting node 1 (not the master ) and tried to issue the same command I get 4 times the following:  
E0731 19:54:41.841061 3339 memcache.go:265] couldn’t get current server API group list: invalid character ‘\<’ looking for beginning of value  
E0731 19:54:41.899273 3339 memcache.go:265] couldn’t get current server API group list: invalid character ‘\<’ looking for beginning of value

E0731 19:54:42.032201 3339 memcache.go:265] couldn’t get current server API group list: invalid character ‘\<’ looking for beginning of value

what night have changed? Thanks

Here is the output when I run  
`kubeadm config print init-defaults`  
on master
