How can I establish connections through k8 nginx ingress which don't close

[pnikhil610]

I've setup Zilla on k8. It works great!

However, I've issue with connections closing at random interval.

Here's how ingress look likes:

I've enabled http/2

Is there any example for ideal k8 nginx ingress setup which I'm missing and is causing this issue?

I want to add that ERR_CONNECTION_CLOSED is new error I started getting after update to v0.9.83 @vordimous

@pnikhil610 I have found some additional settings that can affect the SSE connections through an nginx-ingress controller. Can you update your annotations to add these:

    nginx.ingress.kubernetes.io/proxy-buffering: "off"
    nginx.ingress.kubernetes.io/proxy-request-buffering: "off"
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "21600"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "21600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "21600"

One important thing is to make sure proxy buffering is off so it won't affect the SSE stream itself.
