I am using Elasticsearch client version 8.6
we use Elasticsearch as a service and other companies provided us an IP/port to connect to it.
we run heavy, numerous, automated queries against this Elasticsearch and sometimes I see in the logs that the only Ip/port for this Elasticsearch gets blacklisted and this will cause elasticsearch load imbalance.
