In iOS 16, it always show
-[nw_ip_channel_inbox initWithPath:flow:parameters:delegate:] flow (some uuid interface: utun4, viable, assigned) does not specify local endpoint
after call [NWListener start:].
This issue doesn't happen in iOS 15. Although it looks like a crash, the app keeps working and getting data. What does "specify local endpoint" mean?
