Hello Team,

we are implementing remote cluster with proxy mode. we have noticed that we could able to add only one node as proxy\_address and its opened 18 socket connection to the same node.

we are not able to search the data if configured proxy\_address node is down.

how we can add more proxy\_address for high availability

> "skip\_unavailable" : true

The proxy address is resolved via DNS on each connection attempt, and connection attempts are retried 3 times, so you can achieve high availability by setting it to a DNS name that resolves to multiple addresses in a round-robin fashion.
