cc @guydc
can we bump initDelaySeconds to 10 ?
Sorry for the late reply, I missed that CC.
The issue this time appears to be connection reset/refused and not 404s:

I'm not sure that increasing the readiness time will help in this case. This could be an issue with metallb/kube-proxy forwarding requests to terminated pods.
