Can't connect ipsec vpn

Hi @LucasMo,

Please collect ike debugs: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Understanding-IPsec-iked-debug-logs/ta-p/256321

Regards, 

Can you also show the phase1 parameters on the FCT? 
The IKE debug would need to be run on the FGT while reproducing the issue:
diagnose vpn ike log-filter name <phase1_name>
diagnose debug application ike -1
diagnose debug console timestamp enable
diagnose debug enable

To disable:
diagnose debug disable
diag debug reset
