Changing the port of backend blocks connecting to Neo4j

[icejean]

Hi all, I just build up the project on my Windows with Docker Desktop， running on WSL. As I want to run another WSL instance with jupyterhub that uses port 8000，I want to change the backend port to 8088，I modyfied the file docker-compose.yaml and change the port of backend to 8088, and run docker-compose up --build, it's O.K. to build and start up, but when I try to connect to Neo4j, it's just being blocked there, is there any other place I need to modify too? My docker-compose.yaml, just replace all 8000 with 8088:

version: "3"

Best regarts.

Addressed by modifying port 8000 in ./backend/Dockerfile and .env too.
