I installed ES first, it worked fine. Then installed Kibana, both Kibana and ES worked fine after enabling Authentication as well.
Now installed Logstash, faced issues while starting, now managed to start it but getting below error :
[2019-08-28T16:52:05,410][ERROR][logstash.licensechecker.licensereader] Unable to retrieve license information from license server {:message=>"Unrecognized SSL message, plaintext connection?"}.
Please help.
