Getting the above error:

I've seen this reported a few times, but I'm still not clear on which library, exactly, is failing and where to look for an update that fixes it.

Here's what curl -v reports for flightstats.com:

Is the problem the size of the certificate? The encoding? I wish I knew where to look.
