Unable to start Elasticsearch as a service

Elastic Stack Elasticsearch
5

I also tried to reset the password for Kibana based on this post:
I lost the password that has been changed
I am getting this error for both users Elastic and Kibana.

      ]
    }
  },
  "status" : 401
}

Is there any other way to authenticate the built-in users?
