IKEv2 - Cannot Connect Android, iOS & macOS

zooky

Hi All,

I have setup IKEv2 on my pfSense machine (2.4.4) to authenticate with windows RAS.

Windows machines can successfully authenticate and connect to pfsense no problem but Android, iOS and macOS cannot connect.

My pfsense machine has a wild card certificate installed which i assume is working fine (from what I can tell)

Below are the logs from pfsense after trying to connect from iOS and android
