Kibana throwing errors behind a load balancer

Hello, I have been having some issues where Kibana is throwing me "clear your session" errors

User enter's Kibana, loads a dashboard, a few minutes pass, error occurs

                                         |______ > Server 2: Apache reverse proxy to localhost --- > Kibana 

Full error:

Something went wrong
Try refreshing the page. If that doesn't work, go back to the previous page or clear your session data.

Clear your session

Hey @gborg, this has been reported a few times and it's generally when a reverse-proxy is configured incorrectly and responds in an incorrect manner. Would you mind capturing a HAR of the network traffic when you see this error in the console? walks you through this process.


I am currently on vacation, will do so when I'm back
