The sysdiagnose was taken from our iOS 26 device. We have tested this on all our devices ranging from iOS 15 to iOS 26 and this bug is present on all the versions.

We have a similar issue where sometimes after reinstalling or updating our app the packet tunnel provider fails to start until the phone is rebooted. We see the same "The VPN session failed because an internal error occurred." line when inspecting the sysdiagnose logs but also see these errors: Service could not initialize: access(/private/var/containers/Bundle/Application/5C3DA870-60A6-4A6A-ABF2-2769EA06E069/VPNApp.app/PlugIns/VPNTunnel.appex/VPNTunnel, X_OK) failed with errno 2 - No such file or directory, error 0x6f - Invalid or missing Program/ProgramArguments My guess is the OS is trying to reference the extension in a directory that no longer exists after reinstalling/updating?

Fixed in iOS 26 beta 6

Thanks for the response. Unfortunately, we continue to face this issue sometimes when testing our app on iPhone 15 running iOS 18.1 beta 5. Is there any update regarding this? As this negatively impacts the user experience of our app.

Sorry for the confusion. I can see the .lproj folders for en, de and it for both the app and extension. And the prompt itself is in Italian when the system language is Italian. The issue is, that the English name is being used for the Italian version of the prompt. So going by my previous example, where the English name is VPNAppEN and the Italian name is VPNAppIT, I would expect to see the below message in Italian: "VPNAppIT" desidera aggiungere delle configurazioni VPN But instead I see: "VPNAppEN" desidera aggiungere delle configurazioni VPN How can we get the Italian name to show in the prompt?
