Nexcloud fungerar inte med stack och traefik

🚧 Installation

I’ve done everything to get this stack to run on the docker swarm and I can’t do it.

I’ve been reading articles and making changes for days and nothing works, I’ve never had such a bad experience creating a stack.

I’ll leave you a model of one of the stacks I’ve created, and I hope someone can help me.

networks:
  network_public:

volumes:
  nextcloud_data:
    name: nextcloud_data
    external: true

I already have mysql configured in another container and redis too.

Thank you!
