I want to configure particular cipher suites to be used by filebeat to connect with logstash. While using ssl.cipher\_suites I was getting below error log

{"log.level":"error","@timestamp":"2024-05-28T06:28:10.029Z","log.origin":{"function":"[github.com/elastic/beats/v7/libbeat/cmd/instance.handleError","file.name":"instance/beat.go","file.line":1312},"message":"Exiting:](http://github.com/elastic/beats/v7/libbeat/cmd/instance.handleError%22,%22file.name%22:%22instance/beat.go%22,%22file.line%22:1312%7D,%22message%22:%22Exiting:) error initializing publisher: could not setup output certificates reloader: unpacking 'ssl' config: invalid tls cipher suite 'TLS\_AES\_128\_GCM\_SHA256' accessing 'output.logstash.ssl.cipher\_suites.0' (source:'/opt/filebeat/filebeat.yml')","service.name":"filebeat","ecs.version":"1.6.0"}

And with all same setup I tried with cipher\_suites then it worked.  
Is there any specific configuration I missed or suggestions to check?
