Making Nextcloud Docker accessible from local network - docker

Question

I installed a fully dockerized Nextcloud server on Ubuntu LTS 20.04.
Right now, it is accessible via nginx from the subdomain I assigned to it, with a SSL certificate from Lets Encrypt.
I would like to be able to access it from a local IP from within the network on port 8140.
I tried adding the ports to the docker-compose.yml file with:
ports:
- "8140:8140"
But the ports get assigned to 0.0.0.0 instead of the machine's IP address.
Anyone knows how to expose the container to the local network?
Here's an example of the docker-compose.yml I used:
version: '3'
services:
proxy:
image: jwilder/nginx-proxy:alpine
labels:
- "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy=true"
container_name: nextcloud-proxy
networks:
- nextcloud_network
ports:
- 80:80
- 443:443
- "8140:8140"
volumes:
- ./proxy/conf.d:/etc/nginx/conf.d:rw
- ./proxy/vhost.d:/etc/nginx/vhost.d:rw
- ./proxy/html:/usr/share/nginx/html:rw
- ./proxy/certs:/etc/nginx/certs:ro

As far as I know, you append the IP Address you are binding to locally as follows:
ports:
- 192.168.0.254:80:80
- 192.168.0.254:443:443
- "192.168.0.254:8140:8140"
