Hi Davide,
We are working on supporting Kubernetes 1.22, for now please try with Kubernetes version 1.21

[davidespanu]

by running the command kubectl version I got as an answer
Client Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.5+k3s2", GitCommit:"724ef700bab896ff252a75e2be996d5f4ff1b842", GitTreeState:"clean", BuildDate:"2021-10-05T19:59:14Z", GoVersion:"go1.16.8", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.5+k3s2", GitCommit:"724ef700bab896ff252a75e2be996d5f4ff1b842", GitTreeState:"clean", BuildDate:"2021-10-05T19:59:14Z", GoVersion:"go1.16.8", Compiler:"gc", Platform:"linux/amd64"}

so the version of kubernetes should be 1.21

looks like server version is 1.21 🤔

what does this return?

$ kubectl api-versions

[davidespanu]

in the file below there is what that command returns

api-versions.txt

In the server_name variable you need to specify a domain name and not an IP address.
