the curl -XDELETE http://localhost:9200/.kibana
command works fine, however you lose all your Kibana settings (indexes, graphs, dashboards); by just querying the index I’ve solved the problem, without losing my data. For example:
curl -s http://localhost:9200/.kibana/_recovery?pretty
curl -XPUT 'localhost:9200/.kibana/_settings' -d '
{
"index" : {
"number_of_replicas" : 0
}
}'
Then start Kibana, it should work.
