Error returning discovery document-swift

Our company is working through Okta for login and wants me to integrate it. I follow the IOS tutorial exactly and get this error.

apiError(error: “Error returning discovery document:The operation couldn’t be completed. (OktaAuth.OktaError error 1.) Pleasecheck your PList configuration”)

There is no redirect and the appDelegate as been setup per the walkthrough instructions.

I have filled out both the Okta plist and app plist as specified. Any ideas
