Unable to ADD Worker nodes to a cluster of Raspberry Pis
Once Head node is set up (no issues here), here’s what i have already attempted to add Workers:

  • With config yaml file
  • Without config file i.e. adding manually
  • Playing with ssh with password and without Password (i.e. keys)

Nothing I tried solves the problem. I am on the verge of breaking my keyboard #frustrating
Please help
