Kibana: Unable to fetch mapping. Do you have indices matching the pattern?

[unpluggedcoder]

Kibana version:
6.0.1-1
Elasticsearch version:
6.0.1-1
Server OS version:
CentOS 7.4

Hello, I got stuck on the kibana index setting.
As it shows up in the web:

But I can see the logstash-* index from the "curl localhost:9200/_cat/indices?v"

And the ElasticSearch monitoring page:

So why does this happen? Or is there anything I misunderstood?
Any suggestion will be helpful! Thanks!

I just found the problem, I've logged into Kibana with 'kibana' user, so this happened.
Log in with 'elastic' built-in user will fix this problem.

So, pls close this issue, hope it doesn't bother u guys. 😅
