Hello,
There is an error message below:
2023-04-11 04:56:37.596980 ike 0:VPN-ATS: no suitable IKE_SA, queuing CHILD_SA request and initiating IKE_SA negotiation
I would recommend to check whether phase1 configuration is matching on IPsec peers and remote gateways are correct.
Hello,
We've made sure it's the same configuration.
Could it be because we're using 2 different firewalls?
Best regards,
Hello,
Fortigate supports the VPN connection with the Cisco ASA, in the VPN creation wizard you have the option to select the remote device type Cisco.
Although you cross-checked and found that the setup is the same, the debug logs indicate that IKE SA is not matching. For testing purposes, you can try using the remote device as Cisco in the VPN creation wizard to create a new tunnel.

Yeah .. seems issue is because wrong phase 1 parameters. Please verify the phase1 settings at both end.
no suitable IKE_SA, queuing CHILD_SA request and initiating IKE_SA negotiation
You posted the whole stuff.
Find The solution here
in phase 1 is a wrong parameter as I have already been informed.
Hi,
Can you please check phase1 settings on both side of tunnels. Based on debugs, it seems there's a mismatch in phase1 settings.

Also, please check if DPD is enabled on both the ends.
