Failed to register observatory port with mDNS with error -65555.

See original GitHub issue

I don’t have a reproduction for this, but I have run into a situation where I can launch with flutter run but trying to launch with the VSCode debug button I get this error

[VERBOSE-2:FlutterObservatoryPublisher.mm(101)] Failed to register observatory port with mDNS with error -65555.
[VERBOSE-2:FlutterObservatoryPublisher.mm(103)] On iOS 14+, local network broadcast in apps need to be declared in the app's Info.plist. Debug and profile Flutter apps and modules host VM services on the local network to support debugging features such as hot reload and DevTools. To make your Flutter app or module attachable and debuggable, add a '_dartobservatory._tcp' value to the 'NSBonjourServices' key in your Info.plist for the Debug/Profile configurations.

I’m facing the same problem on vscode, flutter runs on terminal but not on vscode debug,however everytime when I use an IKEv2 VPN the problem disappears.
