FortiClient 6 won't auto connect while 5 would

I am currently working with the new FortiClient 6 and I tried to use the same configuration file as in version 5. We configured auto connect based on a certificate with version 5 and it always auto connected fine. Now with version 6 the client does not autoconnect anylonger instead the GUI shows up and wants me to click connect.

This is my configuration (basically):

And this is what I get on startup instead of the autoconnect: [link=https://forum.fortinet.com/post.aspx?forumID=5] Sample.jpg [/link][strike][/strike]
