Is there anything that has changed upgraded from 0.55.1 to the latest helm charts that would cause this error -

Error binding socket

.

I'd expect to see the iface:port failed to bind, do you see that?

i dont have it offhand at the moment but i believe that was there, its just using the port 2020

how are you deploying it? if you can share a repro, it would be helpful to validate

I deploy it using the helm chart in

<https://fluent.github.io/helm-chartsand|https://fluent.github.io/helm-charts

>and that specific block looks like below. Nothing really out of the ordinary (I dont think) and it works with 0.55.1, anything past that I get the error. I can try to put together a reproducer I have this set to use Kubelet...

dnsPolicy: ClusterFirstWithHostNet
hostNetwork: true

This seem similar if not the same:
