Forti does not send "sa delete" when bringing down tunnel
we have 2 Forti sites with tunnel against same partner gateway.
1 one site the partner receives properly a "sa delete" when I bring down the tunnel.
On the other site not.
Overall both tunnel are working properly. Just the issue is, if for i.e. DPD the tunnel goes down the partner will no see it. So may keep up the Phase1 still, which makes it impossible to get tunnel up again.
Any idea why one of our gateways sends the SA delete and the other not
