Hi, It's global problem in our environment. We cannot open Kibana UI all browsers but Internet Explorer. What might be misconfigured? ELK stack in general looks sane.

Have you recently upgraded Elasticsearch? Possibly a CORS issue and IE is just being extra permissive? You might consider upgrading to Kibana 3.1.2 which has a troubleshooting page to help out with CORS issues, or Kibana 4 which doesn't have CORS issues. Unfortunately the browser doesn't tell Kibana when it fails to contact Elasticsearch due to CORS, it just fails the request. You might try this in your Elasticsearch config. You'll need to restart Elasticsearch. http.cors.allow-origin: "/.\*/" http.cors.enabled: true If that doesn't help, can you open up the firefox developer console and see if you have any errors there? I don't really see any issues in your logs. One is a 304, one is a 200, both are fine responses.
