          ✅ Gitea ist jetzt über Traefik erreichbar!

          {% else %}
          ⚠️  Gitea ist noch nicht erreichbar
          
          Mögliche Ursachen:
          1. SSL-Zertifikat wird noch generiert (ACME Challenge läuft)
          2. Traefik Service Discovery braucht mehr Zeit
          3. Netzwerk-Problem zwischen Traefik und Gitea
          
          Nächste Schritte:
          1. Warte 2-5 Minuten und teste erneut: curl -k {{ gitea_url }}/api/healthz
          2. Prüfe Traefik-Logs: cd {{ traefik_stack_path }} && docker compose logs traefik --tail=50
          3. Prüfe Gitea-Logs: cd {{ gitea_stack_path }} && docker compose logs gitea --tail=50
          4. Prüfe Netzwerk: docker network inspect traefik-public | grep -A 5 gitea
          {% endif %}
