localhost authorization failed cURL com error

I’m new to plugins, but got App Id and Secret for two apps (Slte Exchange and Site Exchange). One was to test adding Facebook connections on http://fdc.local/ my development server and the other for my live site floatingdockcomics.com. When I pressed the authorize button on Slte Exchange for http://fdc.local/, I got:

cURL communication error 60 SSL certificate problem, verify the CA cert is OK.

I don’t know how to clear that error or proceed. Does my development server need SSL certification?
