Hi,
We just followed Head plugin unable to connect to Elasticsearch 5.3 - cluster health: not connected to install head plugin by
./elasticsearch -plugin install x-pack,t when we access localhost:9200/_plugin/head with userid: elastic and passpwrd: changeme, the error messages are as follows:
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"No endpoint or operation is available at [head]"}],"type":"illegal_argument_exception","reason":"No endpoint or operation is available at [head]"},"status":400}
Any advice would be appreciated
