Alright, so setting `--o:server_name=office.example.tld`into collabora’s environment variables fixed the url. But I still havent managed to load any documents yet

What also worked was finding [this](https://help.nextcloud.com/t/no-acceptable-wopi-hosts-found-matching-the-target-host/12392/6) page as well
