Kibana not prompting for credentials after 6.3 upgrade


I had tried the plugin with ELK GA 5.0.0 and when I go to Kibana url, it prompts for credentials, so that I can give admin or readonly credentials. Now, after upgrading to 6.3, Kibana simply loads data without prompting for credentials. I am using Kibana oss 6.3. How can I fix this?

Thank you.


how did you upgrade Elasticsearch ?
and kibana ?

which release and version of RoR ?
do you use RoR pro or enterprise, or did you use basic authentication ?
