"Same problem, newer platform.: Catalina 10.15.7 'A software update is required to connect to iPhone' but downloading 'has a network problem.' Same as other users, newer OS (not using iTunes)."

Connection Issue:

There is an issue connecting the to Apple Server. So, try the following:

1. Disconnect, then Reconnect: to the network connection
2. Power Off: your modem/router
3. Connect: to a different network
4. Try this Later: (utility work may be going on down the street).

Try booting into Safe Mode and then reconnect the iPhone and try installing the update in Safe Mode. Do you have any anti-virus, network security, cleanser/optimizer applications or software installed? Do you have custom firewall settings?
