Brief summary of the bug. What is it ? Where is it ?
Since the update to the elastic client 7.16.3 Optimize is not trying to reconnect to elasticsearch if an initial connection to it failed.
Steps to reproduce:
Run Optimize when Elasticsearch is not yet reachable, wait for a connect exception and then actually start Elasticsearch.
Actual result:
Optimize does not retry to connect, no new logs entries are produced:
