Fix SocketTimeoutException
in ELK Stack
✅ Solution
SocketTimeoutException in Elasticsearch often arises from slow queries or network latency exceeding the client's configured timeout. Increase the `client.socket.timeout` and `client.transport.ping_timeout` settings in Elasticsearch's configuration to allow more time for requests to complete, or optimize slow-running queries to improve their performance. Consider also investigating and resolving any network connectivity issues between the client and Elasticsearch cluster.
