VPN connection fails after restorign from backup

[aag]

Running pfSense on an HP appliance (was on 2.7, but started its life on a much earlier version). Upgrade to 2.7.2 was failing due to undersized EFI partition, so backed up, reinstalled, and restored from backup.

Most things seem to be operational for the moment, but VPN connection (IKEv2) seems to be failing from all provisioned clients.

Are there any known issues with VPN configuration being restored from backup?

Seems to be cypher related, as MacOS client now seems to connect fine, while iOS (17.4.1) still can't.

These are the cyphers currently enabled:

Any idea what's missing for iOS? I can't seem to find any docs on what it requires.
