Hello everyone. Today I have upgraded a RKE cluster from 1.21 to 1.22 with RKE v1.3.12 and after the upgrade, the Nginx Ingress controller became unreachable. Here is what I have gathered so far: • Accessing the controller works from within the pod • Accessing the exposed 80 and 443 ports from the node results in a timeout (not connection refused) • The hostPorts used by the controller doesn’t show using

netstat -nltp

• Found some suggestions on GitHub to use host network for the controller instead of host ports. Tried it, doesn’t change anything. However ports 80 and 443 shows on netstat. • I have applied a workaround by manually creating a NodePort service for the controller and re-configuring our load balancer trough to use the service. Anyone has any ideas why this might happen or any additional steps to debug?
