Kibana fails

[daytonpa (Patrick Hugh Dayton)]

Kibana is not accepting incomming connections, and I cannot find anything regarding this error below. I am not sure if this is a permissions issue, but this error is from /var/log/kibana/kibana.log

If anyone has any input regarding what this error is, I would very much appreciate it.

Kibana version: 5.3.3
Elasticsearch version: 5.6.5
OS: Ubuntu 16.04

It looks like you are setting elasticsearch.shardTimeout in your Kibana configuration, which is not available in 5.3.

Here are the configuration options for 5.3: https://www.elastic.co/guide/en/kibana/5.3/settings.html
