Hello, Following this tutorial [https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-ubuntu-16-04](https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-ubuntu-16-04). Everything was going great, filebeat info are showing up (i was forced to put the insecure:true in the config) I was next trying to install metricbeat the same way i did for filebeat. And i encountered an error sending the information to logstash: If i use a FQDN cert as in the DigitalOcean tutorial i get : `2017-02-08T15:47:22+01:00 ERR Connecting error publishing events (retrying): x509: certificate is valid for , not ec2-34-249-172-152.eu-west-1.compute.amazonaws.com` If i use the IP certs: `2017-02-08T15:57:51+01:00 ERR Connecting error publishing events (retrying): x509: cannot validate certificate for 34.249.172.152 because it doesn't contain any IP SANs` Can someone help with that? Thanks. ---
