Closing as a resolved network configuration issue, from Rancher user slack:

It's working now. I was able to Join K3s ... I had deployed in OpenSTACK - Ubuntu Instance, I was trying to add through Public IP / hostname as server address. That was not working... Once I spin up instace on same private_subnet as master & use private IP as server address ... It's worked ...

Is there an official recommendation on how to deal with this issue?

I've had a similar problem when trying to set up a high availability control plane.

What I did wrong: I've used the --server and the --token parameter. (They are not needed at all for the masters connected via an external backing database like etcd.)

How I was able to solve my specific problem: Use the --bind-address parameter.
