Excluded Elasticsearch autoconfiguration which is included by default, solves the issue for now. My answer approved to disable it. ```auto spring: autoconfigure: exclude: org.springframework.boot.autoconfigure.elasticsearch.ElasticsearchRestClientAutoConfiguration ``` [stackoverflow answer here](https://stackoverflow.com/questions/53606426/rabbithealthindicator-health-check-failed) ---
