404 on install in subfolder

🚧 Installation
,
1

Hi all,
currently i am trying to install a new nextcloud instance using docker (for mac).

I followed the example on github which is running fine from the webserver root. But i want to make nextcloud accessibly from a subfolder like https://domain/cloud so i can have other services on the same domain and ports.

As a first try i changed all the paths inside nginx.conf to forward /cloud requests to the nextcloud container. I double checked the changes according to the nextcloud docu. But i always get a 404 page and a “Primary script unknown” error. On the console 404 says it cannot find /cloud/index.php.

Even if i copy the copy the config of the nextcloud docu, it does not work but with a different error. This time i will get a redirect error without additional prompts in any console.

Nginx logs are also always empty.

This is my docker-compose for the 404 error:

            try_files $uri /cloud/index.php$request_uri;
            # Optional: Don't log access to other assets
            access_log off;
        }
    }
}

Does anybody have an idea how to solve this?

Thanks in advance

Did you set overwritewebroot and overwrite.cli.url?

Hey,
the config.php does not yet exist. The error occurs when i open the installation page, so i cannot run the install process.
But i added overwritewebroot as environment to the docker-compose which does not change anything. Is it possible to add overwrite.cli.url as environment as well? I did not find any docu about that.
