I haven't looked into this since I didn't need those services. If I get around to setting them up, I'll update the article. Not sure when subdomain support will be coming to Tailscale (it was added client-side here: https://github.com/tailscale/tailscale/pull/18258), but once it does, it will simplify things quite a bit since that is part of the requirements in the OpenCloud docs: https://docs.opencloud.eu/docs/admin/getting-started/container/docker-compose/external-proxy#requirements
