.cert vs .pem

Fellow Rocketeer Dillon Hafer had the explanation for my SSL issue mentioned at reactnative -

“DNSimple gives you a cert and a pem file. The cert file is just the certificate, while the pem file is actually 4 certificates mushed into one file. The 3 extra certificates are the intermediate certificates required by some operating systems that only include Root Certificates. Hope that helps explain why the pem from DNSimple works while the cert doesn’t.” - Dillon Hafer
