Hi @devops_yorosis,
To confirm, this forum is best effort help from both Elastic employees and the developer community. It can take time to get an answer, and we advise pinging if you've not received an answer within a couple of working days rather than hours. It is not intended as production support.
We need more information to understand what is going on with your cluster. By:
elastic was not loading
do you mean you are seeing a message such as "Kibana server is not ready"? Or something else? I would recommend following the diagnostic steps here and checking the state using the health API to get more information on the state of your cluster.
Do share the config, log output and health response.
Hope that helps!
