Page not found after running docker compose up on rancher desktop

Hi :)

I cloned the repository, ran ./bootstrap.sh groupfolders inside the repository and started everything with docker compose up -d nextcloud. Everything looks fine so far. I got no errors and can see all container up and running.

When I try to access nextcloud.local, I get a 404 Page not found. Starting nextcloud 2 with docker compose up -d nextcloud2 I get the same issue using nextcloud.local and/or nextcloud2.local. When I then use nextcloud2.local:8211, I get an login screen. I assume its because a port is exposed for nextcloud2. The PORTBASE is defined as 821 in the .env file. The DOCKER_SUBNET in .env is 192.168.21.0/24.

I haven't modified any config file in the repo.

If the content of any of the files is needed for further analysis or any other information, please say what is needed and I will post it :)

As I am not that deep into Docker Compose and Rancher Desktop, I can't find a solution to make it work. Also asking ChatGPT hasn't helped me.

What can I do or what do I have to change in the config files to make it work?

P.S. Using the standalone version (run --rm -p 8080:80 ghcr.io/juliushaertl/nextcloud-dev-php83:latest) works fine.

Start with bootstrap.sh groupfolders, the docker compose commands for nextcloud and nextcloud2, and the PORTBASE and DOCKER_SUBNET values in .env. Compare the compose setup with the standalone command that works, then reproduce the 404 at nextcloud.local and the login screen at nextcloud2.local:8211. Done means the compose services are reachable at the documented hostnames without requiring an unexpected port.
