Hello,

I configured Logstash for netflow packets.  
Devices send correctly packets to my server.  
In /var/log/logstash/logstash-plain.log I can see that logstash recover packets.

The issue is that data are not sent to my Elasticsearch Server.

In /var/log/logstash-stdout.log I have this error =\>

tail -f /var/log/logstash-stdout.log
