Vpn site-to-site (fortigate-to-fortigate) phase 2 failure

Hello, I have a Fortigate 30D (fw v6.0.5) and 60C (fw v5.2.13), FGT-30D have static ip, FGT-60 have dynamic IP (working DDNS with fortiddns.com), both working fine with internet and virtual ips, I create a VPN site-to-site with the wizard, but no connect, the log say nothing, only failure in phase 2, how can I check what is wrong? both devices have automatically created policies and static routes.
The fortigate 60C, have a vpn working fine with forticlient.

    It's very likely the wizard set different proposals for 5.x and 6.x. Make sure there is min one (the same) on both peers:
     
    https://help.fortinet.com/fos50hlp/56/Content/FortiOS/fortigate-ipsecvpn/Phase_2/Config_Phase2_Parameters.htm
     
    Once you confirm settings on both units you can use following debug command:
     
    diag debug app ike -1
    diag debug enable
