Hi,

I need to setup a VPN link between a supplier and our ER-605 as server, with the requirements : 
- IKEv2
- PSK and aes256-sha256-dh14 in phase 1 and phase 2

We must apply these requirements and can't ask to change anything.
The tunnel fails to established with an "error during IKE phase 2" on client side. Can't have more details or logs.
ER605 side : absolutely no logs

Can you check if something's wrong with the config, please ?

ER605 v2.0 stand alone mode
2.2.3 Build 20231201 Rel.32918

Network plan (ER605 is the VPN server) :

Client side :

ER605 conf :
