how to prevent lost data when connection lost in streaming data to logstash?
If the connection to Logstash is unreliable, the clients sending to it need to be able to queue up data so it can be resent when the connection is restored. Beats are e.g. able in recent versions to spool to disk to queue data up in case there is an issue with sending it on.
What does your ingest architecture look like? From where are you collecting data?
