We had an ES+Kibana instance set up a few months back on AWS and it was working fine. Last week I restarted it for a Snapshot backup and noticed the ES and Kibana instances were down.
When I started them up, they were only binding to the local IP and i updated the config file and got them accessible from outside.
But then I noticed all the dashboards we developed were gone and the .kibana index was empty.
How could this happen and is there a method to recover the index. I do have an old snapshot I took just after setting everything up which I already restored and still the same result. Empty index
