Hi,

My team had incorporated TLSv12,TLSv1.1 changes on rabbitmq and because of this logstash cluster got failed. I recovered logstash cluster and updated logstash configurations to ignore rabbitmq inputs.

When i run this command this below error came.

/opt/logstash/bin/logstash -f /ec2-user/logstash-rabbitmq.conf  
Settings: Default pipeline workers: 1

Well, can you connect to port 5671 on 10.5.11.49 from the Logstash host? If not you have a network problem.

That's a different question. Does `telnet 10.5.11.49 5671` work?
