Not able to PUT to ES

[JeroenVdb]

I installed Grafana and ES. Both in a Docker.

When I try to save a Grafana dashboard I get this error in Chrome:

XMLHttpRequest cannot load http://192.168.59.103:9200/grafana-dash/dashboard/grafana. Method PUT is not allowed by Access-Control-Allow-Methods.

I added these configs to my elasticsearch.yml

http.cors.allow-origin: "*"
http.cors.allow-methods: "OPTIONS, HEAD, GET, POST, PUT, DELETE"

Someone has any idea what I'm doing wrong? My apache where Grafana is running should also have correct headers.
