I recently configured https for kibana running in three different environments. One of them works fine while the other two have issue as mentioned below - 1 - {"statusCode":503,"error":"Service Unavailable","message":"License is not available."} I get this error when i try to browse kibana. 2 - "Kibana server is not ready yet" I get this error for the third instance of kibana. Not sure what is wrong as i have same configuration for all the three instances. Please some one help here it is a bit urgent. Thanks! ---

Both of these are the same thing, so you need to check your auth details. > [@auser](#): > > unable to authenticate user [elastic] I wouldn't be using the `elastic` user for Kibana anyway, as that's the equivalent of using root. ---
