I created a KuberNetes cluster via de ControlPanel, with 2 nodes
I also created a LoadBalancer. But whatever I do, de LoadBalancer says that 1 node is down. I tried changing TCP / HTTP etc etc, but nothing helps.
What do I need to do to fix this?
nb: My Rancher droplet (where I import the KB YAML) works fine and says all nodes are running.

What do I need to do to fix this?
Check the logs for the node and share what it says.
$ kubectl describe node <node-name>
This will tell you what is wrong with the node, and you can then get a solution for a specific problem with the node.
