Issue
- When configuring a remote Elasticsearch server the Search > Connections screen shows the error java.lang.RuntimeException: error while performing request.
- The logs show the message: Not a valid protocol version: This is not an HTTP port.
Environment
- Any DXP
- Any Elasticsearch running in Remote mode
Resolution
- Elastic search has two main ports for communication: 9200 and 9300 (by default);
- This error rises if you configured the transport port (9300) as a request port (9200);
- Configure the Network Host Addresses parameter with the search server hostname and the correct request port (9200 in most cases), ex: search:9200
