Hey @balamelangi,
The main error here is that Kibana can't connect to Elasticsearch: `No Living connections`. The fact that Kibana crashes in this case is another smaller issue that is fixed in `master` already.
Make sure you can connect to Elasticsearch and Kibana is configured properly to access it too.
Best,
Oleg

@azasypkin Thanks for your replay. But my elasticsearch is running and I'm able to curl also, but from kibana side I'm unable to curl as well. The **CURL** message shows kibana is not ready.
Thanks,
Bala Melangi

@balamelangi, please turn on Kibana verbose logging `--verbose` and share it if possible or just try to find anything suspicious there by yourself. I'm pretty sure that there is some mistake in `elasticsearch.*` settings in `kibana.yml`.
Best,
Oleg
