FAQ: Elasticsearch "cluster health: Not connected" in Chrome / "Connection refused" script error

FAQ relevant for: all Academy versions

Sometimes on the VDIs you will encounter your Elasticsearch being disconnected which will then mean that the data isn't available for easy viewing and it will also lead to errors in your UI.

If you try to run e.g. a load Elastic ETL script while Elastic isn't connected then you will get an error, for example:

Exception in thread "main" java.net.ConnectException: Connection refused

To reconnect the Elasticsearch service you just need to run the following command anywhere in a terminal window on your VDI:

sudo systemctl restart elasticsearch.service

@Dan_Pryer I tried running the command, but I don't have sudo access to the VDI.
