{"statusCode":503,"error":"Service Unavailable","message":"License is not available."}

Elastic Stack Kibana
1

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.

I wouldn't be using the elastic user for Kibana anyway, as that's the equivalent of using root.

Do you have any article or some reference which I can use to look into it? I am sorry, I am new to these configurations.

Take a look at Setting passwords for native and built-in users | Elasticsearch Guide [8.5] | Elastic.
