VPN Mikrotik to Fortigate 100D

Hello my friends,
I have very strange problem with creating of Ipsec tunnel VPN between mikrotik and Fortigate 100D. I get still error log on my mikrotik with information: 192.168.1.111 failed to pre-process ph2 packet. 192.198.1.111 is wan interface of Fortigate. I have checked eveything 100times, so Authentication, encryption and also DH are the same on both sides. I can also see fortinet as estabilised under Active Peer, but in Policies tab i can see problem: no phase2.
I am very confused. I have also found a very similar topic on last line:
http://forum.mikrotik.com/t/solved-ipsec-mikrotik-to-fortigate-phase2-trouble-pls-help/97572/1

But i dont udestand where t change this mode…and problem is mikrotik or fortinet?
Can you give me some advice please?

Thank you very much for any advice.
