"Access Denied" when I try to execute "curl -XGET localhost:9200"

Hi All.
I try to use elasticsearch for my job.
But I found some error when I use it.

I can connect http://my_id_address:9200 using my browser.

{
status: 200,
name: "Dreadnought",
cluster_name: "elasticsearch",
version: {
number: "1.7.3",
build_hash: "05d4530971ef0ea46d0f4fa6ee64dbc8df659682",
build_timestamp: "2015-10-15T09:14:17Z",
build_snapshot: false,
lucene_version: "4.10.4"
},
tagline: "You Know, for Search"
}

But I can get some date using command line.

curl -XGET my_id_address:9200

......
.....
....

ERROR

The requested URL could not be retrieved


The following error was encountered while trying to retrieve the URL: http://my_id_address:9200/

Access Denied.

Do you know why this error occurred?

Hi,
Looks like a proxy issue. Check your ~/.curlrc.
