ElasticHQ: Unable to Connect to Server! Received Status Code: 0

Question

i am getting below error when i was trying to connect to Elastic HQ. Local instance of elasticsearch is running. Elastic search version is 2.0.0.

in the elasticsearch.yml, http.cors.enabled: true is set

Received the following error:

ElasticHQ: Unable to Connect to Server! Received Status Code: 0. A status code of 0, could mean the host is unreacheable or nothing is listening on the given port. Did you enable CORS?

am i missing something?

    #
    http.port: 9200
    
    http.cors.enabled: true

Answer 1

It works now!. i have to add another entry in elasticsearch.yml

http.cors.allow-origin: "*"
http.cors.enabled: true 
node.master: true
