Kris, The certificate validation process is delegated to iOS (that's where the 0x5 error comes from).
The root certificate it trust can vary a bit by versions of iOS (the list gets expanded). A quick way to see if iOS itself trust the certificate is to use Safari (on the same device) and try the same URL, e.g. "https://api.imgur.com/2/upload.json";.
