iOS16 Beta system local network permission pop-up alert does not display

On the previous version of iOS system, by sending UDP broadcast, the local network permission authorization pop-up alert can be triggered normally, but in iOS16Beta, the pop-up alert will not appear, and the local network permission switch will not appear in the App-related system settings.

Given that this worked on previous systems, your first step here should be to file a bug report about the problem. Please post your bug number, just for the record.

I recommend that you do the following:

1. Delete your app from the device.

2. Run it from Xcode, which will re-install it.

3. In the app, do the thing that should trigger the local network privacy alert.

4. Immediately after that alert doesn’t show up, trigger a sysdiagnose log and note down the time.

Include the log and the time stamp from step 4 in your bug report.

Did you end up filing a bug report for this? I am seeing the same issue on iOS 16 Beta 5.

I get no LAN permission dialogue, but LAN access still works. Clean install on both app and iOS device.

Our users have been seeing the same issue on the production release of iOS 16. The restart workaround mentioned by WJohn does work (and we are now instructing users to restart their phones), but this definitely feels like a big miss and something that should be fixed.

However the bigger problem remains -- two iOS versions later and Apple still has not given developers a way to properly trigger the local networking permission programmatically or check it's status programmatically with a sane API and not needing to resort to these sorts of workarounds.

Our users have been seeing the same issue on the production release of iOS 16.

Did anyone end up filing a bug about this? If so, what was the bug number?

We are experiencing this as well on the official release in ios16 webkit where we are loading a development site with unsigned certs over SSL. The fraudulent website warning displays, but when we click proceed the page infinitely reloads. Restarting the phone did fix this, but only for the first set of certs provided, after that trying to load different development apps using unsigned certs results in the same behavior

The problem is still present, is there a fix or a "human workaround" that we can do for the final users?

This bug is still present in iOS 18.3, Is there any timeline for this bug to be fixed?

recently updated to iOS 26.5 and now i have this issue

There have been a bunch of fixes to local network privacy since the start of this thread, including significant fixes for both iOS (I can’t remember the exactly release, sorry) and macOS (in one of the later macOS 26 builds). Given that, experience from previous OS releases is unlikely to be relevant.

For example, one of the bugs mentioned upthread, FB11538990, was fixed in iOS 16.

If you continue to have local network privacy problems on iOS 26, or later releases of macOS 26, my advice is:

1. Review TN3179 Understanding local network privacy, which has a lot of the important backstory here.

2. Try to isolate the problem to a specific local network operation. If you escalate an issue that’s something “my app has local network privacy problems” then that’s unlikely to get traction.

   For an example of the sort of isolation I’m talking about, see this thread. VictorPetitjean’s persistence and skill is what allowed us to finally fix one of local network privacy’s more annoying problems.

3. Start a new thread here on the forums with the details of your issue. Put it in the App & System Services > Networking and tag it with both “Network” and “Privacy”. That way I’ll be sure to see it go by.
