IPSEC VPN certificate authentication

Hello

I'm trying to authenticate remote vpn clients by certificate only. Ive found youtube video that shows how to prepare certificates (this is ssl vpn example). I did everything needed for this to work... i wished.

Unfortunately my FortiClient wont connect. After enabling debug in FC and click 'connect' I get this:

2017-07-10 22:28:11    Debug    VPN    pki_get_mycert() name = testcert CA 2017-07-10 22:28:11    Debug    VPN    AuthDaemon. Message in pipe 2017-07-10 22:28:11    Debug    VPN    AuthDaemon. CSP_AND_CERTNAME 2017-07-10 22:28:11    Debug    VPN    AuthDaemon. Certificate returned 2017-07-10 22:28:11    Debug    VPN    pki_get_mycert() return mycert null !!!! 2017-07-10 22:28:11    Notice    VPN    ike_cfg_gw_init failed check the vpn gateway configuraiton 2017-07-10 22:28:13    Debug    VPN    AuthDaemon. Message in pipe 2017-07-10 22:28:13    Debug    VPN    AuthDaemon. Got Quit message. 2017-07-10 22:28:13    Debug    VPN    authentication finished

Client machine is Windows10, i have installed client (testcert) certificate, also 'server' and CA in desperation but with no luck (either on local user/machine accounts).

There is no traffic between client and FG. When I switch to preshared key authentication I can see ike debug results on my FG.

Any help would be appreciated.
