Issue: Kibana Cannot Connect to Elasticsearch​

When you access Kibana via a web browser, you may encounter the following error:

Fatal Error Kibana: Unable to connect to Elasticsearch Error: Unable to connect to Elasticsearch Error: Bad Gateway ...

To solve this issue:

  • Ensure that Elasticsearch is running (see Elasticsearch troubleshooting).
  • Check the YAML file kibana.yml to verify if the connection between Kibana and Elasticsearch is well configured, that is, if the specified host and port of Elasticsearch are correct.
