[elasticsearch.server][WARN] caught exception while handling client http traffic, closing connection Netty4HttpChannel

Hi,
I get the following error in the cluster log about every hour.

[elasticsearch.server][WARN] caught exception while handling client http traffic, closing connection Netty4HttpChannel

Any suggestions on where to start troubleshooting this error? The network is stable and the cluster load is light so I think those two areas are good.

Thanks

Something is trying to access Elasticsearch using http instead of https may be?

But may be you should share more logs?
