We have timeout error on worker clients who use ES

go client:

```
time="2021-08-02T16:04:45Z" level=error msg="error handling connection with queue: error saving bulk: error making bulk request dial tcp 20.96.122.135:9200: connect: connection timed out" queue=***

```

c# client:

```auto

I don't understand what is occouring. Can you help us with it?

Tried without success: OS:

- sysctl -w net.ipv4.tcp\_keepalive\_time=20
- sysctl -w net.ipv4.tcp\_keepalive\_intvl=20

ES:

- xpack.watcher.bulk.size: 5mb
- xpack.http.default\_connection\_timeout: 60s

Welcome to our community! 😃

What do your Elasticsearch logs show?  
What version are you running?

> - xpack.watcher.bulk.size: 5mb

That's unlikely to be of much use.
