NSURLSession "HTTP load failed kCFStreamErrorDomainSSL, -9813 ; Self signing certificate

Question

I\'m trying to connect my iOS app to an HTTPS Rails app which is currently run on a local host in my network. I can access the site from my browser with https://myIP:3

Answer 1

(Edit - I misread this as 9814, expired cert. I'm not sure how to solve this one, but hopefully my response helps point in the right direction.)

Looks like a cert issue different from the usual "Allow Arbitrary Loads" question.
