Stuck at "Waiting for API to be available"

Actually I realized some searching that “Waiting for API to be available” usually points some misconfiguration somewhere. So I decided to tear down all the nodes and then did the following :

  1. Prepared the nodes based on their roles [which I think is what I underestimated in the previous occasion]
  2. Ran the RKE binary 1.2.13 with its corresponding K8s 1.20 version which it supports.
  3. Boom ! - It worked like a charm and then imported that into the UI…

I will post a detailed documentation what I exactly did , but thats for later. Thanks
