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
