The global bouncer middleware banned all IPv6 ingress: Traefik sees one shared/SNAT'd v6 source, so a single http-admin-interface-probing hit (the e2e scan) 403'd every v6 client. Remove the global entrypoint-middleware attachment; keep the plugin + Middleware CRD inert so re-enabling is one line after fixing client-IP visibility + adding an internal whitelist. Detection (agents) stays on.
