Hello ​@Ajal I think the problem is with the certificate on which you should check with Fortinet if the IP’s of client, network gateway, CS is all whitelisted and the certificate on the client is trusted on Fortinet. 

You can try to pause/stop the SSL validation on the client and that should allow to register the client. 

Best,
