The SSL HTTP connection to:

On your platform your OpenSSL implementation is broken.

There is no difference between the values of VERIFY_NONE and VERIFY_PEER.

This means that attempting to verify the security of SSL connections may not
work.  This exposes you to man-in-the-middle exploits, snooping on the
contents of your connection and other dangers to the security of your data.

To disable this warning define the following constant at top-level in your
