I have an app where I hit a HTTP Request
This problem only happens in iOS 9 since Apple made some changes impacting URL schemes.
I think that one of your libraries is checking to see if you are running on a jailbroken device by checking if it can open cydia://URL...
"Up until iOS 9, apps have been able to call these methods on any arbitrary URLs. Starting on iOS 9, apps will have to declare what URL schemes they would like to be able to check for and open in the configuration files of the app as it is submitted to Apple"
