Nodeport SFTP / SSH connection timeout when using kube-proxy ipvs

kubernetes ssh sftp

So after discussing the whole thing on github the behaviour is intended. When using kube-proxy with ipvs the service is not reachable by the ipvs0 interface. https://github.com/kubernetes/kubernetes/issues/93674#issuecomment-669200021

ipvs is down by default and is just a dummy network without traffic.In the documentation it's written like

The default for --nodeport-addresses is an empty list. This means that kube-proxy should consider all available network interfaces for NodePort.

But ipvs0 is not reachable - this is intended.So the answer is: You should use a real address of the node.
