I'm not super familiar with Kibana 4.6 anymore, but this error is pretty common when using a proxy (apache in your case) that isn't properly setup to talk to Elasticsearch. If you open the network debugging tab in your browser you should be able to see the requests that are being sent and the responses received, do those responses seem to be coming from Apache (they will probably be HTML formatted)? If you access those URLs directly in another tab or with `curl` are you able to talk reach Elasticsearch? What configuration are you using to proxy these requests? I'm not an very familiar with Apache but there might be someone else on the forums who can spot check your configuration.
