CSRF token from either the request body or request headers did not match or is missing. after new install

Hi all,
After a clean install on a debian 12 VM on proxmox, following the guide from https://www.passbolt.com/docs/hosting/install/ce/debian/

I can add / edit / delete passwords, but can’t edit settings.
is-authenticated.json?api-version=v2 is okay,
settings.json?api-version=v2 returns me the CSRF Token error.

My healthcheck looks good :


     ____                  __          ____
    / __ \____  _____ ____/ /_  ____  / / /_
   / /_/ / __ `/ ___/ ___/ __ \/ __ \/ / __/
  / ____/ /_/ (__  |__  ) /_/ / /_/ / / /
 /_/    \__,_/____/____/_.___/\____/_/\__/
