I have a regular app using httputils2 to get some data from my remote app. Today , an update for this app is rejected saying :

Performance - 2.1

We were unable to complete our review of your app as it crashed on launch. Your app was reviewed on iPhone running iOS 10.2.1 connected to an IPv6 network.

Next Steps

Please revise your app and test it on a device while connected to an IPv6 network (all apps must support IPv6) to ensure it will launch without crashing.


For additional information about supporting IPv6 Networks, please refer to Supporting IPv6 DNS64/NAT64 Networks and Supporting IPv6-only Networks.

What are they meaning ? I always update my apps without any problems , what may be the reason for this ?_
