There is no HTTPS, that I'm aware of, used internally in an Elasticsearch cluster - the master and data nodes all communicate over TCP while client requests (from web browser etc) are done over HTTP, not HTTPS. Even Kibana, when you connect that to a node, uses HTTP.

So if you have an expired HTTPS certificate it shouldn't affect your cluster's operation.

Ah, I'm sorry, then I guess an expired HTTPS certificate could be a problem

I'm not using Shield myself so I'm afraid I can't help you there.
