Describe the bug:

After installation of RKE2, Ingress only available for first server node. nginx ingress controller deployed as DaemonSet and pods are running state.

Steps To Reproduce:

• fresh install RKE2.

Expected behavior:
Ingress ports 443 and 80 should be accessible from all nodes which ingress controller installed.

When I tried https://docs.rke2.io/known_issues#ingress-in-cis-mode this policy, I lost access from first server too.

Are you sure that you don't have a host firewall blocking access to those ports? There's nothing in the default configuration that would do what you're describing.

Firewall service is disabled.
Interestingly, Ingress started working on one of the nodes after an unexpected reboot. Is there any service that could affect the functioning of Ingress?

Not that I'm aware of. Have you checked the pod status to make sure that everything's running where it should? What's the output of kubectl get pod -o wide ?
