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.

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?

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

when I call [http://localhost:5000/elasticsearch](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
