No response from peer error

[INT1]

When i try to connect to vpn through IPSEC IKv2 on specific devices its giving me no response from peer. i tried everything and even opened the specific ports on the firewall and router thought maybe it could block the connection and still the same issue.

Check ike debug on the receiving end (FGT):

> diag vpn ike log filter clear
> diag vpn ike log filter dst-addr4 <public IP of your client>

> diag debug app ike 63

> diag debug enable
