Welcome! I see you've posted log snippets without a lot of context. Can you please give more information such as the version of Elasticsearch you are using, how you are running Elasticsearch, what behaviour you are seeing or what issue you are trying to solve?
Looking at the logs snippets I see a couple of potential issues:
- You have an authentication issue:
- There is an issue finding the master node:
If it's your first time spinning up the cluster you may need to set property cluster.initial_master_nodes as covered here. Alternatively I would look at this article which discusses some potential causes.
Hope that helps!
