Helllo, can you give more information? Are you running from source? What version of Kibana is this?

Hi Marius , Version is 6.6.2
It is configured in ubuntu server , logstash and elastic search both are running,
In fact kibana was working fine, but suddenly after update it stoped.
When i execute command service kibana start , it says started, than again when i check status it says not running
