I am trying to activate an application which sends my serial number to a server. The send is being blocked. The app is signed but not sandboxed. I am running Sequoia on a recent iMac. My network firewall is off and I do not have any third party virus software. I have selected Allow Applications from App Store & Known Developers. My local network is wifi using the eero product. There is no firewall or virus scanning installed with this product. Under what circumstances will Mac OS block outgoing internet connections from a non-sandboxed app? How else could the outgoing connection be blocked?

My app uses the top navigation panel which contains the back button, a title, and prompt. On an actual device, the navigation area is light and shows all three items. On the simulator, the navigation area is black and only the back button is shown. I need this to be correct for app store screen shots.
