User Omaticon has a suggestion to configure this module (https://una.io/view-product/elasticsearch). "Do note that the API URL in the module must be formatted as "<HTTP Protocol>://<ElasticSearch IP>:<Specified Query/Ingest Port>. An example is "https://localhost:9200". 

But we could not get the module to connect to our own Redis server. Using http://<server ip>:<default port 6379> as suggested (also tried without the http:// part). We also didn't set any password for the default Redis user. Did anyone else successfully set up this module?
