when I use hosts: ["192.168.26.130:5046","172.16.26.170:5046","172.16.26.171:5046"]  
on logstash output.  
neither loadbalance: true or false,the filebeat always connect the first ip,and others raise

2018-05-02T14:34:09.679+0800 ERROR pipeline/output.go:74 Failed to connect: dial tcp 172.16.26.171:5046: i/o timeout

Even if the first ip shutdown,others won't work also.

this question only display the port 5046.others machine on others ports it's ok.

Have you tried to ping each host?

If ping works, can you try `telnet <ip> 5046`?

Have you checked logstash logs?
