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:

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
2

I tried increase xpack.http.timeout and xpack.watcher.bulk.size without success

Welcome to our community! :smiley:

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

That's unlikely to be of much use.
