Are you connecting an IP address or using a DNS name? If using DNS name - did you have right record in public resolvers?

Any IPSec vpn troubleshooting always starts with confirming reachablility, pinging IP/name while sniffing at FGT side. When you see them in sniffing, you now know the source (NATed) IP address, so that you can use it to filter IKE debugging.

  diag debug reset

  diag vpn ike log-filter dst-addr4 [the_source_IP]

  diag debug app ike -1

  diag debug ena

I would  1st make sure the  diag snifffer packet <insert the expected interface > "port 500 and 4500" shows your hitting the fortigate.

 

Also  double check proposals ( is aggressive  mode set, keyid type, pre-share key  etc....)
