Hi,

could you please clarify what you mean by the UI is not working. Can you execute a curl -v against the URL of your Kibana, and post the output here?

Cheers,
Tim

Hi Timroes,
Thanks for your response.. I execute a curl -v against the URL of kibana and posted here. I installed and configure kibana three months back it is working fine but suddenly i am not able to hit kibana URL (UI Web Page)
can you please help me to solve this problem..

Thanks

Could you please execute another curl -v -L <url>, to follow the redirect. Also maybe it's worth clearing your browsers cache or trying a different browser to see if you're able to access it.

Also just to make sure: You're executing curl from the very same machine, you are trying to access it via the browser?

Usually when Kibana "suddenly" is not accessible anymore, in most cases I've seen, something changed in your infrastructure (proxies started working differently, reverse proxies had changed behavior, cloud routing changed, etc.)

Cheers,
Tim
