Hey.
Thank you for this issue.
When reading the exception message I see that you got error 56. The exception guides you to a page (http://curl.haxx.se/libcurl/c/libcurl-errors.html) that describes the what error 56 means. It says:

Failure with receiving network data.

Failing to receive network data could be because the server is not reachable. This is not caused by an issue with Guzzle.
