@miminar Thanks for the report. Is this just the connectivity tests breaking, or NodePort breaking as a whole?

It's not just the connectivity test. Although a connection to a node port always works from the host network, a connection from the pod network fails. And only for a particular node (the first one):
root@net-debug:/# for h in eu-k8s-dev-{01..10}.euler.ethz.ch; do curl -I --connect-timeout 1 http://$h:32346 |& grep '^HTTP' || echo "$h: BAD"; done
eu-k8s-dev-01.euler.ethz.ch: BAD
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
HTTP/1.1 200 OK
Tested with services of type NodePort and LoadBalancer - same results. FWIW, the node has been re-added to the cluster:
$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
eu-k8s-dev-01.euler.ethz.ch Ready compute,control-plane 2d20h v1.30.1+k0s
eu-k8s-dev-02.euler.ethz.ch Ready compute,control-plane 17d v1.30.1+k0s
eu-k8s-dev-03.euler.ethz.ch Ready compute,control-plane 17d v1.30.1+k0s
eu-k8s-dev-04.euler.ethz.ch Ready compute 2d20h v1.30.1+k0s
eu-k8s-dev-05.euler.ethz.ch Ready compute 16d v1.30.1+k0s
eu-k8s-dev-06.euler.ethz.ch Ready compute 16d v1.30.1+k0s
eu-k8s-dev-07.euler.ethz.ch Ready compute 16d v1.30.1+k0s
eu-k8s-dev-08.euler.ethz.ch Ready compute 16d v1.30.1+k0s
eu-k8s-dev-09.euler.ethz.ch Ready compute 9d v1.30.1+k0s
eu-k8s-dev-10.euler.ethz.ch Ready compute 9d v1.30.1+k0s
But the same goes for eu-k8s-dev-04.euler.ethz.ch
where this cannot be reproduced.
The connectivity test happens to choose the first node for the node port readiness check, that's why it fails reliably.
After a rollback to 1.15.4, I cannot reproduce anymore with any kind of node port.
