your compose file is little strange…

- AFAIK ports and expose is mutually exclusive - you should choose only one  
(sounds you are using my old confg from [Docker Compose for Nextcloud + Collabora + Traefik? - #2 by wwe](https://help.nextcloud.com/t/docker-compose-for-nextcloud-collabora-traefik/127733/2) - better use following post by bluepuma77)
- [_domain_ setting is outdated since ages](https://help.nextcloud.com/t/important-changes-regarding-cool-code-docker-versions-from-v21-11-3-6-on-multiple-domains-setup/137867)
- why did you comment out  
`# - 'traefik.http.services.collabora.loadbalancer.server.port=9980'`

please review
