Rails 4 Dragonfly Gem with Amazon S3 direct download

Question

I'm trying to figure out how to turn on S3 with a dragonfly. This stone works locally, but since I use Heroku, the files are deleted ... so I think I need to implement it in S3.

I use this gem: dragonfly-s3_data_store , where my dragonfly.rb looks like this:

/config/initializers/dragonfly.rb

require 'dragonfly'
require 'dragonfly/s3_data_store'

# Configure
Dragonfly.app.configure do
  plugin :imagemagick

  url_format "/media/:job/:name"

  datastore :s3,
    bucket_name: 'thelab',
    access_key_id: '{my access key}',
    secret_access_key: '{my secret key}',
    region: "us-west-1"
end

... #more code

This is my mistake when I try to upload an image:

hostname "thelab.thelab.s3-us-west-1.amazonaws.com" does not match the server certificate (OpenSSL::SSL::SSLError)

I'm not sure what causes the problem, but also on my console, I see this popping up:

[fog][WARNING] fog: followed redirect to thelab.s3-us-west-2.amazonaws.com, connecting to the matching region will be more performant

There is inconsistency here ... I also tried to switch the region to us-west-2, but I still get the same errors and warning signs.

the form:

= simple_form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f|
  = f.file_field :image
  = f.button :submit, "Save changes"

And, of course, the model, in this case user.rb, has the following:

dragonfly_accessor :image

Am I missing something else I need to configure?
