S3 connection timeout with IAM

[jamesrbrindle]

Everything works perfectly when using file storage, am trying to upload to an S3 bucket but getting the following error:

[fog][WARNING] Unable to fetch credentials: connect timeout reached
[fog][WARNING] Unable to fetch credentials: connect timeout reached

):

dragonfly.rb configured as follows:

require 'dragonfly'
require 'dragonfly/s3_data_store'

# Configure
Dragonfly.app.configure do
  plugin :imagemagick

  secret "-- desensitised --"

  url_format "/media/:job/:name"

#  datastore :file,
#    root_path: Rails.root.join('public/system/dragonfly', Rails.env),
#    server_root: Rails.root.join('public')
  datastore :s3,
    bucket_name: AWS_S3_BUCKET,
    access_key_id: AWS_ACCESS_KEY_ID,
    secret_access_key: AWS_SECRET_ACCESS_KEY,
    region: 'eu-west-1',
    use_iam_profile: true,
    url_scheme: 'https',
    fog_storage_options: {
        :provider => "AWS",
        :aws_access_key_id => AWS_ACCESS_KEY_ID,
        :aws_secret_access_key => AWS_SECRET_ACCESS_KEY
    }

end

This might be more concerned with Fog than dragonfly but any chance you can help with a little diagnosis.

The AWS_ACCESS_KEY_ID and SECRET work fine with the aws-sdk gem and I can manually put files no problem.

I was thinking about doing a fork for aws-sdk but it seems pointless to duplicate what Fog is supposed to do if its fog's issue.

Thanks.

Changing your policy as this gist did will help.

I was experiencing the same issue with IAM. Removing use_iam_profile and setting the correct region (I was using eu-central) solved the problem.

you can't use both use_iam_profile and access keys as documented on the readme:
:use_iam_profile # boolean - if true, no need for access_key_id or secret_access_key
