FortiClient VPN connection error..

Hi,

I'm trying to connect the Client to a VPN Tunnel to use internet, this error keeps popping up when attempting to connect via Remote Access in FortiClient: The server you want to connect requests identification, please choose a certificate and try again. (-5).

My Debug:

FortiGate-VM64 # [131:root:6]allocSSLConn:276 sconn 0x7f5f8640e800 (0:root) [131:root:6]SSL state:before/accept initialization (192.168.90.50) [131:root:6]SSL_accept returned 0.

[131:root:9]Destroy sconn 0x7f5f86410800, connSize=0. (root)

I have tried most of what is online possibilities, disabled certificates in CLI, SSLv3, matched it with TLS1.1, and 1.2 in Internet Explorer as well, still same error.

I know it's certificate related but I'm using a VM of the Firewall, not sure how to get by it..

Thank You
