Marvel behind reverse proxy?

I am trying Marvel behind a reverse proxy setup on Nginx and Apache 2.2 on CentOS 6.6 and I am having problems.

when I access

I get the error

{"error":"ElasticsearchIllegalArgumentException[No feature for name [marvel]]","status":400}

but am fine with straight access via

  "status" : 200,
  "name" : "Blaquesmith",
  "cluster_name" : "CLUSTERNAMEr",
  "version" : {
    "number" : "1.5.2",
    "build_hash" : "12ff9868b4c8a0c45860bebb259e21980778ab1c",
    "build_timestamp" : "2015-04-27T09:21:06Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  "tagline" : "You Know, for Search"

and don't have an issues with via reverse proxy either

curious what i am missing ?

am facing similar error. Did you manage to workaround?

It worked for me when I install Marvel and Sense plugin to Kibana and then access it using marvel agent on elastic node.

How did you get ElasticHQ to work with a RP?
