The error I get in Console is: nw_path_libinfo_path_check [4976A259-3720-4B3C-BB42-62A331B959A6 IPv4#78ff62aa:1997 tcp, legacy-socket, attribution: developer] libinfo check path: unsatisfied (Local network prohibited), interface: en0, ipv4

Hi Quinn, I have exactly the same problem on macOS 15.1 and the latest 15.2. Install the app, first time it accesses the local network the dialog appears. I grant permission and Local Network access works. Reboot the machine, launch the app, now local network access fails. Go into System Settings -> Privacy & Security -> Local Network and I can see my app as Local Network permission. Toggle it off and back on, and local network access starts working again. Happy to provide a copy of my app, it doesn't require a licence. Regards James Milne FilmLight Ltd.
