Open Stack

Hello,
i have been trying to fix a problem for over 2 weeks with no success so am looking for some help as my openstack is due to work in september (for my students).
I need the vpnaas service.
I'm doing a lab with centos / kolla-ansible / victoria ... vpnaas works, exactly what I need.
I replace V with Wallaby. Exactly the same server, the same Centos, I just change V to W in the configuation file. Everything works except Vpnaas.
I have a new server, and for some reason I can't have Victoria (issue with horizon that I don't understand). I'm trying Wallaby. Everything works perfectly except Vpnaas. Why ? It's incomprehensible. A bug ?
The error message (neutron-l3-agent.log):

Command: ['mount', '--bind', '/var/lib/neutron/ipsec/8b987595-47be-45cc-95f5-3b70d24f4976/var/run', '/var/run'] Exit code: 0 Stdout:  Stderr: 2021-07-16 12:03:57.089 281941 INFO neutron_vpnaas.services.vpn.common.netns_wrapper [-] /var/lib/neutron/ipsec/8b987595-47be-45cc-95f5-3b70d24f4976/var/run has been bind-mounted in /var/run
Command: ['ipsec', 'whack', '--status'] Exit code: 33 Stdout:  Stderr: whack: Pluto is not running (no "/run/pluto/pluto.ctl »)

Can this be a bug? I do exactly the same things, the same configurations? How to find the problem? Does anyone have a working Oopenstack Wallaby with Centos and Vpnaas?
Meci in advance for your help.
