Can not login on kibana after upgrade to 6.3

Elastic Stack Kibana

There's lots of things that might cause this, and it's not clear from your post exactly how you upgraded and what settings you are running with.

Regarding your upgrade:

  • How did you perform your upgrade?
  • Are you using the same data directory as you used on 6.2.4?
  • Did you change any configuration?

Can you connect to the Elasticsearch server using curl (or a similar tool)?

  • Does curl -uelastic http://localhost:9200/ work?

Check GET /_xpack on your elasticsearch server.

  • what license type is it reporting?
  • what does it report for the enabled & allowed states on the security feature?
