Relevant issue in Elasticsearch forums: https://discuss.elastic.co/t/elasticsearch-5-6-license-renewal/206420
I think this is because this API is not available in elastic 5.6
JitteryCoyote63 Not sure how/why the X-Pack feature was on (it is not used by the system), but you can disable it with an environment variable in the docker-composexpack.security.enabled=falseShould solve the problem ...
JitteryCoyote63 This seems like exactly what you are saying, elastic license issue...
JitteryCoyote63 next week is the Trains next release with upgrade to ES 7, do you want to wait or sort a solution for this one ?
(BTW: I think that you can mount a license file or delete one, and it should be okay, I'll ask the backend guys regradless)
Well it is there, do you have it in your docker-compose as well?

I was able to fix by applying for a license and registering it
Bottom line is: trains-server uses elastichsearch image: http://docker.elastic.co/elasticsearch/elasticsearch:5.6.16 which does not have an unlimited license (only free license that expires after some time). From versions 6.3, elasticsearch provides an unlimited free license. Trains should use >=6.3, WDYT?
JitteryCoyote63 There is a basic elastic license that should always be there. If for some reason it was deleted/expired then the following command should fix it:
curl -XPOST ' http://localhost:9200/_xpack/license/start_basic '
AgitatedDove14 Yes I have the xpack security disabled, as in the link you shared (note that its xpack.security.enabled: "false" with brackets around false), but this command throws:
{"error":{"root_cause":[{"type":"parse_exception","reason":"request body is required"}],"type":"parse_exception","reason":"request body is required"},"status":400}
