ES 2.3.3 Kibana 4.5.1

One Django-based proxy (revproxy) was used ahead of kibana.

The kibana can be reached via the proxy, but got the error as below:

Oops!

Looks like something went wrong. Refreshing may do the trick.

Please give a hint for me, Thanks.

Hmm, this could be one of several different things. What are the relative URLs used to access Kibana at the proxy? Are you using the server.basePath setting?

3

At the proxy, root (/) is used wthout setting the server.basePath in kibana config

4

Hmm okay. Are you getting any errors inside the browser console?

5

I am using kibana behind node http-proxy and I am also facing the same issue

In console, I am getting this error:

when I call http://localhost:5000/elasticsearch.. it works..that means there is no problem connecting to elastic from kibana using this proxy..so I am unable to understand what the issue is
