Hello. Upgraded from 4.5 kibana, 2.4 logstah, and 2.4 elastic search. But if the to be more precisely I just did a new install with a new config files in order to use x-pack to have authentification so as I was not applicable with an old version of kibana and even with iis application request routing and URL rewrite module. Logging with default elastic user, or with default kibana user (is it the root cause)? Issue is reproducible for both users.
