Hi all, I also try to integrate Authentik and Mailcow. In my setup Mailcow lives behind a Traefik reverse-proxy and my Authentik instance is currently not publicly available, only in my LAN/VPN, also via Traefik. Is this somehow similar to what you tried to setup? Or is your Authentik instance publicly available? Because I cannot successfully test the connection during the configuration in Mailcow’s admin UI 🙁
(If that helps: I can however properly use Authentik for my Nextcloud that also only is available inside my LAN/VPN).
