Hi, With iOS-17.4 update, we are seeing AppProxy VPN not getting started when Apps (associated with PerAppVPN) tried to access network resource after MDM PerAppVPN profile install/update.

Looks like PerApp rules associated with applayer vpn profile are broken after profile update/install as we see internet sites working without going through VPN (appProxy network extension), this start working if we toggle WiFi and then access network resource from Apps associated with PerAppVPN.

Created FB13688086 with all the details for this iOS 17.4 and AppLayerVPN, looking for and update here and any feedback/pointers will help. Thanks

Hi, same here. We can replicate the issue with different per App solutions of different MDM systems. Workaround for us is to restart the device. After restart the per App VPN is triggered correctly for the per App VPN Apps. Safari Domains in VPN Profile seems to work. We just see the problem with Apps using per App VPN.

@eskimo: Thanks for the reply, and slightly similar issue seen with macOS 14.4.1 update and many customers are facing this. Need help on this.

I don’t think there’s any code-level workaround for FB13688086, and that’s all DTS can help you with. If this is causing grief for your customers, I recommend that you work with one of them to escalate it to Apple Support.

We've been seeing this exact issue on all 17.4.x devices as well. Although I see no updates or release notes from Apple on this, the 17.5 Beta 4 update looks to address it on my test devices. When I downgrade back to 17.4.1 on the same iPad, the issue comes back. I am hoping this fix holds through the official release.
