Kubernetes integration stopped working

Hello,

I'm doing Kubernetes intergation. I had a working solution, but it stopped working. I'm out of ideas, maybe someone can help how to debug it.

In restjavad-audit.0.log I see something like this:

[I][130][29 Mar 2018 10:55:10 UTC][ForwarderPassThroughWorker] {"user":"local/admin","method":"POST","uri":"http://localhost:8100/mgmt/shared/authn/login","status":200,"from":"192.168.100.94"}

I used to see a lot of other entries here plus I've seen entries about creationg of pools, nodes in audit log.

When I create an Igress I see that one of the nodes is trying to communicate to F5:

13:01:11.718375 IP 192.168.100.94.56322 > 192.168.2.109.https: Flags [R.], seq 1686613753, ack 3495393884, win 851, options [nop,nop,TS val 0 ecr 5336149], length 0

I'm using version 1.4.2 and pod looks just fine:

My Ingress looks like this:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress
  namespace: kube-system
  annotations:
    virtual-server.f5.com/ip: "192.168.220.242"
    virtual-server.f5.com/partition: "kubernetes"
    kubernetes.io/ingress.class: "f5"
spec:
  backend:
    serviceName: nginx
    servicePort: 80

I've also tried it on other box 13.1 no success, my box is in 12.1.3.1.

Do you have any idea how to debug it futher?
