My app showing network error in iOS 14.2(IPhone 7), resetting the network settings also not working and the problem still persists with error “No route to host”, It seems something blocking communications back to destination server.
App fails to send requests on the local network (through CFSocketSendData) on the iOS 14 device, even the local network access being properly granted so what could be the fix ??
Fix : The real culprit was ForticlientVpn as FortiClient SSL VPN split tunneling does not work for DNS resolution. SSL custom DNS replaced system DNS so the vpn client uninstallation did the trick.
