Change mongodb listening port

[b2r66sun]

I change the mongodb port from 27017 to 27018 because 27017 has already been used for another db service, but I got this log.

05:03:26 <INFO:SLF4JLogger> Exception in monitor thread while connecting to server localhost:27017

So I'm wondering whether the mongodb port shouldn't be changed?
docker-compose:

version: '3'
services:
  mongodb:
    image: mongo
    restart: unless-stopped
    ports:
      - "27018:27017"
    volumes:
      - /data/grasscutter/db:/data/db
  grasscutter:
    image: siakbary/dockergc:ubuntu-dev-5.7
    command: -d 'mongodb://mongodb:27018' -b 'localhost' -f 'yes'
    restart: unless-stopped
    volumes:
      - /data/grasscutter/resources:/home/Grasscutter/resources
    ports:
      - "22102:22102/udp"
      - "23337:443/tcp"
      - "23336:80/tcp"
    depends_on:
      - mongodb
    stdin_open: true
    tty: true

port 27018 you can access outside containers (public) and port 27017 you can still use inside containers because it only communicates between containers, isolated from the outside
