Not working #1
Description
Tried to use your blog post advice to permit mocking of AWS requests, kept failing.
Cloned this repo so I could confirm I wasn't crazy:

18:26:29.603 [error] GenServer ExAws.Config.AuthCache terminating
** (RuntimeError) Instance Meta Error: {:error, %{reason: :timeout}}
You tried to access the AWS EC2 instance meta, but it could not be reached.
This happens most often when trying to access it from your local computer,
which happens when environment variables are not set correctly prompting
ExAws to fallback to the Instance Meta.
Please check your key config and make sure they're configured correctly:
For Example:
\`\`\`
ExAws.Config.new(:s3)
ExAws.Config.new(:dynamodb)
