Disable VPN
VPN or proxy connections might prevent your device from contacting the update servers.
Contact the VPN Service provider and disable it for the time being. In some cases, if the VPN server or network is configured to block certain domains or IP addresses, it might inadvertently block Apple's update servers. This could prevent your device from connecting to Apple's servers to download the update. Make sure that the VPN settings do not block Apple-related services.
