i assume that you are using the VPN Only version of FortiClient and not one managed by a EMS.

if so, https://docs.fortinet.com/document/fortigate/7.6.1/administration-guide/710480 try disabling ems-sn-check, which is enabled by default starting with 7.6 

 

as for phase-2 selectors, i would leave the default ones for src and dst 0.0.0.0/0

 

L.E. https://community.fortinet.com/t5/FortiGate/Technical-Tip-IPsec-dial-up-full-tunnel-with-FortiClient/ta-p/189452#:~:text=Note%3A-,In%20v7.6%20and%20above%2C,-in%20the%20IPSEC
