Hi,  
when I’m trying to execute :  
`sudo kubeadm init --control-plane-endpoint=192.168.1.2 --node-name k8s-ctrlr --pod-network-cidr=10.244.0.0/16`

I got this error :  
`[init] Using Kubernetes version: v1.28.4 [preflight] Running pre-flight checks error execution phase preflight: [preflight] Some fatal errors occurred: [ERROR Port-10250]: Port 10250 is in use [preflight] If you know what you are doing, you can make a check non-fatal with `–ignore-preflight-errors=…` To see the stack trace of this error execute with --v=5 or higher`

when I run :  
`netstat -ltnp | grep -w ":10250"`

`tcp6 0 0 :::10250 :::* LISTEN - `  
what should I do please ?

thanks
