I'm having some problem setting up Kibana, seems like it can't reach Elasticsearch.
I'm using ELS 2.3 with a modified Kibana 3.1.3 which was made to work with ELS 2.
After a while with this set up, Kibana stopped working, or more like it seemed like it couldn't reach ELS anymore, can't load or save a Dashboard, it tells me:
Failed to save to Elasticsearch
I can only try to access to the default Logstash dashboard.
By opening Firefox's developing tool, Network says I'm connected to my ELS server and there are no errors in all the queries (_search, _search count etc...)
Anyway, no data are fetched, no visualisation at all though I can see the mapping of my indices in Field at the bottom.
To me, it's a problem of Kibana unable to reach ELS, but it used to work so I'm confused. Maybe some NGINX problem ?
