Hi Tom,

leftsendcert is set. Here are the details of the config :

conn %default
        keyexchange=ikev2
        ikelifetime=60m
       
ike=aes256-sha256-modp2048,aes256-sha1-modp1024,aes128-sha1-modp1024,3des-sha1-modp1024!
        esp=aes256-sha1,aes256-sha1,3des-sha1!
        dpdaction=restart
        dpddelay=60s
        dpdtimeout=300s
        keyingtries=5
        inactivity=4h
        lifetime=4h
        left=strongswan.restena.lu
        [email protected]
        leftauth=pubkey
        leftsendcert=always
        leftcert=strongswan.restena.lu-cert.pem
        leftsubnet=0.0.0.0/0,::/0
        right=%any
        rightauth=pubkey
        rightsendcert=always
        rekey=yes
        reauth=yes
        mobike=no

Apart from the default, every user is idenfied by it's certificate CN
and is assigned to an IP pool

conn IKEv2-tech-ctompers
        rightid="..."
        rightsourceip=%pool-v4,%pool-v6
        auto=add

We already had this issue in former versions when the native client was
doing only IKEv1.

kind regards,
Claude
