What is timing out in this error. It is timing out to connect to Elastic?

Hard to tell with the little info that you provided, but it could be that it's timing out connecting to Elastic. The version that you are using is a bit outdated in the way timeouts are handled though. I would recommend to update the low-level client version that you are using. If you use only low-level client, its version does not have to match the server version.

We are using Rest High level client. It is same for High level client, version does not have to match the server version?

I thought you were using the low-level client. If you are using the high-level client, the client version does matter and needs to match the server version.

What do you mean with "using rest client multiple times in production" ? Do you create multiple instances of the client in your application?
