We got 3 different environments running Elastic Search - Development, Test and Production. But recently we started to get the error "Maximum number of retries reached" when creating an Index from a C# program, but only in the test environment. It's a cluster with 2 nodes.
This is the exact exception thrown: "Elasticsearch.Net.ElasticsearchClientException: Maximum number of retries reached. ---> System.Net.WebException: The remote server returned an error: (400) Bad Request."
I hope that someone in this group can give me a hint, what to search for?
