Hello !
I get the enclosed message when running the "kubeadm join" statement from the worker window (Lab 2.2. Deploy a New Cluster, p3)

Could you help me ?

Hi @jolymakit,

Your peer learners have posted similar issues in the past, and the solution that seemed to fix it was the selection of a different subnet for the VMs. From what I recall the 10.2.0.0/16 subnet worked.

Hello @chrispokorni ,
The issue happens because I was using "europe-west9" region on my VPC and WM.
I switched to "us-central1-a"
It's weird, but everything works now....
Thanks for your help.
Regards
