Hey @DTS Engineer / @davidprivorostrauss Thank you guys for your answers. I was able to reproduce this problem on an small and basic test app. And regarding your thoughts about iOS 18 I can confirm that the exact same code works wonderfully under iOS 16 - on a different device though. Thanks

@DTS Engineer A couple more things, the bug is reproducible in different iOS 18 devices. I have a very basic sample app which uses NWListener, NWConnection and NWBrowser. The bug is reproducible only when I try to connect to a host & port, but If connect through Bonjour the bug doesn't happen, everything works as expected. Thanks.

@DTS Engineer I can confirm that I can reproduce the problem on my side using your exact same code - which is pretty similar to mine - and using a local http server on my Mac computer. It worked well the first time, then I deleted the app and installed again and did the exact same steps and the issue is reproducible. The only way to fix it is to restart my device. I am on iOS 18.1. Then I tried the same code on an iOS 16 device, I tried the same steps deleting the app three times and I was not able to reproduce the bug on that device. I appreciate your help, Thanks

@DTS Engineer It seems that after updating to iOS 18.1.1 the bug is not reproducible anymore. Thanks.

@DTS Engineer / @Eric-L You are right, the issue is still reproducible on iOS 18.1.1
