Site-Site VPN issue

Question

Hi Guys, I have some issue for Sophos. Recently I have purchase a Fortinet Firewall at Malaysia and original I'm using Sophos Firewall in SG. I trying to set site to site VPN for both of them but it failed. Fortinet I already set up SG public IP and connection between them. The same thing I also do in Sophos Firewall. I raised support ticket to Fortinet, they mentioned XG side is not sending quick-mode message hence the phase2 tunnel does not go up.

Hello, 
 we have several Sophos to Fortinet site-to-site Tunnels running, this should not be a general problem. 
 Could you post a screenshot of the details of the "IPsec profile" for thar connection from the Sophos firewall side? 
 Then we need the equivalent definitions from the Fortinet side as well. You can partially obfuscate the public IP, if you wish.
